POLYMER BLEND COMPOSITIONS CONTAINING A STYRENIC COPOLYMER, AN ACETAL POLYMER AND A THERMOPLASTIC POLYESTER OR POLYCARBONATE RESIN INGREDIENT |
摘要 |
The present invention pertains to thermoplastic polymer blends which comprise a monovinylidene aromatic copolymer, an acetal polymer and a thermoplastic polycarbonate resin or a polyester resin derived from the reaction of a dicarboxylic acid and a glycol, and which may also optionally contain an elastomeric material such as a thermoplastic polyurethane or an elastomeric copolyester. The resulting polymer blends have good processability and a beneficial combination of physical and chemical properties including thermal/dimensional stability, impact resistance, chemical resistance and environmental stress crack resistance. Said polymer blends are suitable for use in the preparation of a variety of molded utilitarian articles having good appearance and paintability. C-37,455-F
