A weather-resistant polyacetal resin composition being excellent in weatherability and has a reduced surface glossiness while maintaining good mechanical properties, high frictional wear resistance and good mouldability inherent in polyacetal, which is produced by blending:
(A) 100 parts by weight of a polyacetal resin with
(B) 0.01 to 5 parts by weight of a weathering (light) stabiliser and
(C) 1 to 50 parts by weight of a core shell polymer consisting of a core of a rubber-like polymer and a shell of a glasslike polymer comprising a vinyl copolymer having an oxygen-containing polar group.
Moulded product obtained therefrom can be suitably used in interior automotive trims which should have an appearance suggestive of high-quality and a good weathering (light) resistance while avoiding the reflection of light, and for the production of optical instruments, building materials and household goods.
一种耐候性聚
缩醛树脂组合物,具有优异的耐候性和较低的表面光泽度,同时保持了聚
缩醛固有的良好机械性能、高摩擦耐磨性和良好的成型性,这种组合物是通过混合生产的:
(A) 100 重量份的聚
缩醛树脂与
(B) 0.01 至 5 份(按重量计)老化(轻质)稳定剂和
(C) 1 至 50 份(按重量计)的芯壳聚合物,芯壳聚合物由橡胶类聚合物和
玻璃 类聚合物组成,
玻璃类聚合物包括具有含氧极性基团的
乙烯基共聚物。
由此获得的模塑产品可适当用于汽车内饰件,这些内饰件应具有高质量的外观和良好的耐候性(耐光性),同时避免光反射,还可用于生产光学仪器、建筑材料和家庭用品。
