✦ Synopsis

Abstract

The kinetic aspects of the bisphenol‐A polycarbonate–polybutylene terephthalate exchange reaction are considered as a function of temperature and of the PC/PBTP ratio. The most likely mechanism is a direct reversible ester‐ester interchange reaction catalyzed by titanium residues present in commercial PBTP.

Ternary poly(butylene terephthalate) (PBT)/bisphenol-A-polycarbonate (PC)/poly(hydroxyether of bisphenol-A) (phenoxy) blends, with PBT contents from 0 to 30% were obtained by melt-mixing. The presence of PBT clearly increases the ductility of the already rather ductile PC/phenoxy blends. The increas
