High heat distortion resistant segment ester polycarbonates

Segment-ester polycarbonates have improved resistance to high heat distortion when portions of the polymer contain units derived from 4,4'-cyclohexylidenediphenol and derivatives thereof. Preferred high heat distortion segment-ester polycarbonates include the copolyestercarbonate with segments...

Zusammenfassung:	Segment-ester polycarbonates have improved resistance to high heat distortion when portions of the polymer contain units derived from 4,4'-cyclohexylidenediphenol and derivatives thereof. Preferred high heat distortion segment-ester polycarbonates include the copolyestercarbonate with segments derived from isophthalic acid and 4,4'-cyclohexylidenediphenol and/or terephthalic acid and 4,4'-cyclohexylidenediphenol. Films made of the segment-ester copolycarbonates have improved resistance to high heat distortion.
