Unusual Behavior of Poly(methylhexylsiloxane) Short Chain Molecules in Solution

Abstract This work reported the study of the second virial coefficient ($ A_{2} $) and molecular conformation experimental value in good solvent for polysiloxane short chains whose substituent’s connected to the silicon are a larger alkyl side group ($ C_{6} %$ H_{13} $) and $ CH_{3} $.

520			\|a Abstract This work reported the study of the second virial coefficient ($ A_{2} $) and molecular conformation experimental value in good solvent for polysiloxane short chains whose substituent’s connected to the silicon are a larger alkyl side group ($ C_{6} %$ H_{13} $) and $ CH_{3} $. The analysis of the conformation show a slope for poly(methylhexylsiloxane) (PMHS) chains consistent with a spherical conformation. Surprisingly, the $ A_{2} $ experimental value indicates that toluene is good solvent, so long-range interactions occur. This unusual behavior indicates that large alkyl groups have a profound effect on the molecular conformation because the PMHS adopt a compact conformation in a good solvent. The theoretical–experimental behavior of $ A_{2} $ was done considering the effects of the large side group on the main chain, molecular conformation, and molecular weight. The calculation is based on the following theories; unperturbed dimensions obtained from the analytical theory of connectivity-induced correlations, Kurata-Yamakawa of ψ (interpenetration function), Yamakawa-Tanaka of αs2 (gyration-radius expansion factor), and Yamakawa-Stockmayer of $ A_{2} $.

The analysis of the conformation show a slope for poly(methylhexylsiloxane) (PMHS) chains consistent with a spherical conformation. Surprisingly, the $ A_{2} $ experimental value indicates that toluene is good solvent, so long-range interactions occur. This unusual behavior indicates that large alkyl groups have a profound effect on the molecular conformation because the PMHS adopt a compact conformation in a good solvent. The theoretical–experimental behavior of $ A_{2} $ was done considering the effects of the large side group on the main chain, molecular conformation, and molecular weight. The calculation is based on the following theories; unperturbed dimensions obtained from the analytical theory of connectivity-induced correlations, Kurata-Yamakawa of ψ (interpenetration function), Yamakawa-Tanaka of αs2 (gyration-radius expansion factor), and Yamakawa-Stockmayer of $ A_{2} $.

The analysis of the conformation show a slope for poly(methylhexylsiloxane) (PMHS) chains consistent with a spherical conformation. Surprisingly, the $ A_{2} $ experimental value indicates that toluene is good solvent, so long-range interactions occur. This unusual behavior indicates that large alkyl groups have a profound effect on the molecular conformation because the PMHS adopt a compact conformation in a good solvent. The theoretical–experimental behavior of $ A_{2} $ was done considering the effects of the large side group on the main chain, molecular conformation, and molecular weight. The calculation is based on the following theories; unperturbed dimensions obtained from the analytical theory of connectivity-induced correlations, Kurata-Yamakawa of ψ (interpenetration function), Yamakawa-Tanaka of αs2 (gyration-radius expansion factor), and Yamakawa-Stockmayer of $ A_{2} $.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Poly(methylhexylsiloxane)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Unperturbed dimensions</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Molecular weight</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Molecular conformation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Second virial coefficient</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cervantes, J.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of inorganic and organometallic polymers and materials</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V., 1991</subfield><subfield code="g">21(2010), 1 vom: 24.

title_auth	Unusual Behavior of Poly(methylhexylsiloxane) Short Chain Molecules in Solution
abstract	Abstract This work reported the study of the second virial coefficient ($ A_{2} $) and molecular conformation experimental value in good solvent for polysiloxane short chains whose substituent’s connected to the silicon are a larger alkyl side group ($ C_{6} %$ H_{13} $) and $ CH_{3} $. The analysis of the conformation show a slope for poly(methylhexylsiloxane) (PMHS) chains consistent with a spherical conformation. Surprisingly, the $ A_{2} $ experimental value indicates that toluene is good solvent, so long-range interactions occur. This unusual behavior indicates that large alkyl groups have a profound effect on the molecular conformation because the PMHS adopt a compact conformation in a good solvent. The theoretical–experimental behavior of $ A_{2} $ was done considering the effects of the large side group on the main chain, molecular conformation, and molecular weight. The calculation is based on the following theories; unperturbed dimensions obtained from the analytical theory of connectivity-induced correlations, Kurata-Yamakawa of ψ (interpenetration function), Yamakawa-Tanaka of αs2 (gyration-radius expansion factor), and Yamakawa-Stockmayer of $ A_{2} $.
