<p><P>PROBLEM TO BE SOLVED: To provide a polycarbonate composition having a high thermal deformation resistance and improved bending fatigue strength. <P>SOLUTION: The polycarbonate composition contains (A) 82-99.5 wt.% of at least one kind of polycarbonate based on one or more cyclic aliphatic bisphenol expressed by formula (1a) and (B) 0.5-18 wt.% of at least one ethylene alkyl acrylate block copolymer. In the formula, R<SB>1</SB>and R<SB>2</SB>are mutually independently hydrogen, halogen, 1-8C alkyl, 5-6C cycloalkyl, phenyl or 7-12C aralkyl; n is an integer of 4 to 7; R<SB>3</SB>and R<SB>4</SB>are individually selective in each X and mutually independently hydrogen or 1-6C alkyl; and X is carbon, however, R<SB>3</SB>and R<SB>4</SB>are simultaneously alkyl about at least one X. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
