Styrenic copolymer/polyacetal/thermoplastic polyurethane or elastomeric copolyester blend compositions |
摘要 |
Thermoplastic polymer blends comprising a monovinylidene aromatic copolymer, an acetal polymer and an elastomeric material such as a thermoplastic polyurethane or an elastomeric copolyester have good processability and a beneficial combination of physical and chemical properties including thermal/dimensional stability, impact resistance, chemical resistance and creep resistance. Said polymer blends are suitable for use in the preparation of a variety of molded utilitarian articles having good appearance and paintability.
