Modification of Polybutyleneterephthalate and Polycarbonate Block Copolymers Containing Pyrrole Rings

The physicomechanical properties of polybutylene terephthalate and polycarbonate composites with the unified modifier block copolyphenylene-ether-ketone-sulfone-pyrroloxime were investigated. Addition of up to 1% modifier increased the thermal stability of the composites and changed the melt flow index to values suitable for processing.
