发明名称 Transparent two phase polyester-polycarbonate compositions
摘要 Polymer compositions comprising: (A) at least one polyester (A) comprising: (1) diacid residues comprising about 70 to 100 mole percent phthalic acid residues; and 0 to about 30 mole percent of modifying dicarboxylic acid residues, wherein the total mole percent of diacid residues is equal to 100 mole percent; and (2) diol residues comprising about 0 to 45 mole percent 1,4-cyclohexanedimethanol residues, and 100 to about 55 mole percent of other alkylene glycol residues, wherein the total mole percent of diol residues is equal to 100 mole percent; and (B) a miscible blend of: (1) at least one polycarbonate (B) of bisphenol A; (2) at least one polyester (C) consisting essentially of 1,4-cyclohexanedicarboxylic acid residues and at least one glycol selected from 70 to 100 mole percent of residues of 1,4-cyclohexanedimethanol residues and 0 to 30 mole percent of residues of polytetramethylene glycol.
