摘要

Disclosed are compositions of matter characterized by having a tensile strength of at least 13,000 psi (914 kg/cm<2>) and moldable at temperatures below 285 DEG C comprising a blend of (a) 10-95 weight % of a polyester containing repeating units from trans-4,4 min -stilbenedicarboxylic acid 1,6-hexanediol, and (b) 90-5 weight % of a polycarbonate of 4,4 min -isopropylidenediphenol. o
