Patent ID: 6969745

Claim:
A thermoplastic composition comprising; 1 to 30 weight percent, based on total weight of said thermoplastic composition, of a cycloaliphatic polyester wherein said cycloaliphatic polyester consists essentially of repeating units of formula: wherein R 7 and R 8 are independently at each occurrence selected from the group consisting of an aliphatic group having 6 to 20 carbon atoms and a cycloalkane having 6 to 20 carbon atoms, with the proviso that at least one of R 7 and R 8 is a cycloalkyl containing radical; and greater than or equal to 40 weight percent, based on total weight of said thermoplastic composition, of a polyorganosiloxane/polycarbonate block copolymer, wherein said composition has a B-Y span of less than or equal to 20.
