Abstract

See full text

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.degree. 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.degree. 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.
