Determination of catalyst active sites distributions in ionic polymerization

Abstract

The authors propose the method for analysis of kinetic heterogeneity of ionic coordinating polymerization active sites. Tikhonov regularization procedure was used for calculation of active sites distribution on kinetic activity based on experimentally obtained molecular weight distribution curves of polydienes. The polymodal shape of the resulting curves demonstrates the presence of several types of active sites and that their kinetic activity varies during the polymerization of dienes.
