Problems of Polymer Modification and the Reactivity of Functional Groups of Macromolecules

Abstract

Generalapproach to the study of kinetics and mechanism of macromolecular reactions in comparison with the reactions with low molecular substances is developed. The neighbouring group effect in the transformation of functional groups of macromolecules is considered on the experimental basis of chlorination reaction with parafines, cycloparafines and polyethylene, acid and base hydrolysis of polymethyl methacrylate and polydiphenylmethyl methacrylate of different microstructure and of quatemization of polyvinyl pyridine. The effect of microtacticity and of conformational peculiarity on kinetical behaviour of various polymeric samples in polymeranalogous reaction is considered. A ~new computer technique to calculate the individual rate constants for macromolecular reactions is described and the theoretical approach to estimate the units distribution sequences and the composition heterogeneity of the products is developed.
