Provided is a shaped article for clean rooms comprising a resin composition prepared by melt-kneading 100 parts by weight of a cyclic olefin polymer (A) having a glass transition temperature of from 60 to 200°C, from 1 to 150 parts by weight of a flexible copolymer (B) prepared by polymerizing at least two monomers selected from a group consisting of olefins, dienes and aromatic vinyl-hydrocarbons, and having a glass transition temperature of 0°C or lower, from 0.001 to 1 part by weight of a radical initiator (C), and from 0 to 1 part by weight of a polyfunctional compound (D) having at least two radical-polymerizable functional groups in the molecule. The shaped article for clean rooms has good chemical resistance, heat resistance and dimensional accuracy, it is inhibited from releasing a volatile component around it, and it has good abrasion resistance and is inhibited from producing particles.
本发明提供了一种用于洁净室的成型制品,该制品包括一种树脂组合物,该树脂组合物是通过熔融捏合100份(重量)玻璃化转变温度为60至200℃的环烯烃聚合物(A)制备的;1至150份(重量)柔性共聚物(B),该柔性共聚物是通过聚合至少两种选自烯烃、二烯烃和芳香族乙烯基烃的单体制备的,玻璃化转变温度为0℃或更低;0.001 至 1 重量份的自由基引发剂 (C),以及 0 至 1 重量份的多官能化合物 (D),其分子中至少有两个可自由基聚合的官能团。洁净室用异型制品具有良好的耐化学性、耐热性和尺寸精度,可抑制周围挥发性成分的释放,具有良好的耐磨性,并可抑制颗粒的产生。
