Japanese Patent JP3159140

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a polyester resin composition having heat resistance higher than those of a binary compatible polycarbonate (PC)/1,4-cyclohexanedimethanol(CHDM) derivative copolyester system and a binary incompatible PC/CHDM derivative copolyester system and having good mechanical properties.
SOLUTION: This composition comprises a polyester (A) comprising dicarboxylic acid units based on terephthalic acid(TPA) units and glycol units based on ethylene glycol(EG) units (I) and CHDM units (II) and having a (I) to (II) molar ratio of 1 or above, a polyester (B) comprising dicarboxylic acid units based on TPA units (II) and glycol units based on EG units and CHDM units (II) and having a (I) to (II) molar ratio of below 1, and an aromatic PC (C).
