| 摘要 |
A polymer composition for electrical part material comprising, (I) a polymer blend which comprises (A) at least one polymer selected from specific types of polyether imides and polyesters, and (B) at least one polymer selected from specific types of polyphenylene ethers, polyolefins, and polycarbonates, and (II) a copolymer of maleic anhydride and vinyl type compound or (II') an epoxy-modified styrene-type copolymer. The composition has excellent compatibility, heat resistance, mechanical characteristics, platability, moldability, and electric characteristics. It is an ideal material for use as an electrical part material due to its low dielectric constant and low dielectric dissipation factor at high frequency.
