Effect of reprecipitation on the molecular characteristics of PAK PM polyamidoacid
Conclusions The reprecipitation of solutions of PAK PM polyamido acid of various molecular weights and concentrations has been investigated. It has been found that the process of reprecipitating PAK PM is not accompanied by polymer degradation. The constants of K and α in the Mark-Kuhn-Houwink equat...

| 520 | |a Conclusions The reprecipitation of solutions of PAK PM polyamido acid of various molecular weights and concentrations has been investigated. It has been found that the process of reprecipitating PAK PM is not accompanied by polymer degradation. The constants of K and α in the Mark-Kuhn-Houwink equation for the original and reprecipitated PAK PM specimens have been obtained. It has been shown that the decrease in intrinsic viscosity of PAK PM on reprecipitation is caused by an effect of conformational changes in the macromolecular bundle. The authors thank A. É. Gal' for taking the IR spectra. | ||

Effect of reprecipitation on the molecular characteristics of PAK PM polyamidoacid |
| abstract |
Conclusions The reprecipitation of solutions of PAK PM polyamido acid of various molecular weights and concentrations has been investigated. It has been found that the process of reprecipitating PAK PM is not accompanied by polymer degradation. The constants of K and α in the Mark-Kuhn-Houwink equation for the original and reprecipitated PAK PM specimens have been obtained. It has been shown that the decrease in intrinsic viscosity of PAK PM on reprecipitation is caused by an effect of conformational changes in the macromolecular bundle. The authors thank A. É. Gal' for taking the IR spectra. © Plenum Publishing Corporation 1986 |
