## Abstract The existence of interchange reactions in a poly(ethylene 2,6βnaphthalenedicarboxylate)/poly(bisphenolβA carbonate) blend (PEN/PC) has been proven by means of solubility tests, DSC and FTIR and NMR spectroscopies. In addition, DSC results reveal that these interchange reactions are resp
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
