The possibility of applying a titanium-magnesium nanocatalyst in the polymerization filling of polyolefins and some properties of the obtained composites
Abstract The possibility of applying a titanium-magnesium nanocatalyst during in situ polymerization of ethylene and propylene in the presence of organomodified aluminum silicates and diatomite under mild conditions is investigated. How the substantial (2- to 3-fold) increase in the catalytic activi...

520 | |a Abstract The possibility of applying a titanium-magnesium nanocatalyst during in situ polymerization of ethylene and propylene in the presence of organomodified aluminum silicates and diatomite under mild conditions is investigated. How the substantial (2- to 3-fold) increase in the catalytic activity of the system depends on the type and amount of filler is shown. The activity of the titanium-magnesium nanocatalyst-filler system during polymerization of propylene is 3–4 times higher than that during the polymerization of ethylene. Composites based on ultrahigh-molecular-mass polyethylene (M = (1.4–1.7) × $ 10^{6} $) with 3.5–13.0 wt % filler are obtained. According to DSC and X-ray structural-analysis data, the polyethylene matrix differs by its high crystallinity and a Tm of 143–144°C. The physicochemical characteristics of the composites are 1.5–2.0 times greater than those of unfilled polyethylene; the nanocomposite containing 11 wt % mont-morillonite modified with vinyltrimethoxysilane has the best properties. It is shown that during the propylene polymerization, the effect of the type of filler affects not only the catalytic activity of the system, increasing it three times in the case of diatomite, but also the stereospecificity of the effect. Isotactic high-molecularmass (up to 390 × $ 10^{3} $) polypropylene is obtained in the presence of montmorillonite containing vinyltrimethoxysilane, while a low-molecular-mass ((65–75) × $ 10^{3} $) polymer with lower isotacticity is formed on diatomite. The deformation-strength characteristics of composites based on polypropylene testify the formation of an elastomeric material with Tm = 156–158°C. | ||

How the substantial (2- to 3-fold) increase in the catalytic activity of the system depends on the type and amount of filler is shown. The activity of the titanium-magnesium nanocatalyst-filler system during polymerization of propylene is 3–4 times higher than that during the polymerization of ethylene. Composites based on ultrahigh-molecular-mass polyethylene (M = (1.4–1.7) × $ 10^{6} $) with 3.5–13.0 wt % filler are obtained. According to DSC and X-ray structural-analysis data, the polyethylene matrix differs by its high crystallinity and a Tm of 143–144°C. The physicochemical characteristics of the composites are 1.5–2.0 times greater than those of unfilled polyethylene; the nanocomposite containing 11 wt % mont-morillonite modified with vinyltrimethoxysilane has the best properties. It is shown that during the propylene polymerization, the effect of the type of filler affects not only the catalytic activity of the system, increasing it three times in the case of diatomite, but also the stereospecificity of the effect. Isotactic high-molecularmass (up to 390 × $ 10^{3} $) polypropylene is obtained in the presence of montmorillonite containing vinyltrimethoxysilane, while a low-molecular-mass ((65–75) × $ 10^{3} $) polymer with lower isotacticity is formed on diatomite. The deformation-strength characteristics of composites based on polypropylene testify the formation of an elastomeric material with Tm = 156–158°C.

How the substantial (2- to 3-fold) increase in the catalytic activity of the system depends on the type and amount of filler is shown. The activity of the titanium-magnesium nanocatalyst-filler system during polymerization of propylene is 3–4 times higher than that during the polymerization of ethylene. Composites based on ultrahigh-molecular-mass polyethylene (M = (1.4–1.7) × $ 10^{6} $) with 3.5–13.0 wt % filler are obtained. According to DSC and X-ray structural-analysis data, the polyethylene matrix differs by its high crystallinity and a Tm of 143–144°C. The physicochemical characteristics of the composites are 1.5–2.0 times greater than those of unfilled polyethylene; the nanocomposite containing 11 wt % mont-morillonite modified with vinyltrimethoxysilane has the best properties. It is shown that during the propylene polymerization, the effect of the type of filler affects not only the catalytic activity of the system, increasing it three times in the case of diatomite, but also the stereospecificity of the effect. Isotactic high-molecularmass (up to 390 × $ 10^{3} $) polypropylene is obtained in the presence of montmorillonite containing vinyltrimethoxysilane, while a low-molecular-mass ((65–75) × $ 10^{3} $) polymer with lower isotacticity is formed on diatomite. The deformation-strength characteristics of composites based on polypropylene testify the formation of an elastomeric material with Tm = 156–158°C.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Polymer Science Series</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Diatomite</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TIBA</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Olefin Polymerization</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Polymerization Filling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mendeleev, D.

Abstract The possibility of applying a titanium-magnesium nanocatalyst during in situ polymerization of ethylene and propylene in the presence of organomodified aluminum silicates and diatomite under mild conditions is investigated. How the substantial (2- to 3-fold) increase in the catalytic activity of the system depends on the type and amount of filler is shown. The activity of the titanium-magnesium nanocatalyst-filler system during polymerization of propylene is 3–4 times higher than that during the polymerization of ethylene. Composites based on ultrahigh-molecular-mass polyethylene (M = (1.4–1.7) × $ 10^{6} $) with 3.5–13.0 wt % filler are obtained. According to DSC and X-ray structural-analysis data, the polyethylene matrix differs by its high crystallinity and a Tm of 143–144°C. The physicochemical characteristics of the composites are 1.5–2.0 times greater than those of unfilled polyethylene; the nanocomposite containing 11 wt % mont-morillonite modified with vinyltrimethoxysilane has the best properties. It is shown that during the propylene polymerization, the effect of the type of filler affects not only the catalytic activity of the system, increasing it three times in the case of diatomite, but also the stereospecificity of the effect. Isotactic high-molecularmass (up to 390 × $ 10^{3} $) polypropylene is obtained in the presence of montmorillonite containing vinyltrimethoxysilane, while a low-molecular-mass ((65–75) × $ 10^{3} $) polymer with lower isotacticity is formed on diatomite. The deformation-strength characteristics of composites based on polypropylene testify the formation of an elastomeric material with Tm = 156–158°C. © Pleiades Publishing, Ltd. 2014 |
