Synthesis and properties of unsaturated block copolyether ketones

Abstract

Block-copolyether ketones containing >C=CCl2 groups, characterized by high thermal and mechanical properties, with quantitative yield and high values of reduced viscosity, were obtained based on various oligomers with condensation degrees of n = 1-20 using the method of acceptor-catalytic polycondensation. The structure of the resulting polyesters was confirmed. The kinetics of polyester structuring at the site of the double bond depending on temperature and dwelling time was studied.
