## SYNOPSIS The physical, thermomechanical, and rheological properties of bisphenol A-tetrabromobisphenol A copolycarbonates (BA-TBBA COPCS) were studied as a function of copolymer composition. TBBA carbonate segments in the copolymer induce proportionally increased glass transition temperatures,
A new class of copoly(ether-carbonate)s was synthesized using a melt polycondensation reaction of the bis(hydroxyethyl ether) of bisphenol A with bisphenols and diphenyl carbonate. Copolymers with a wide range of values T g (62Γ140Β‘C) were obtained. The copolymer structures were established by 1H NM
