Title:
MOLDED ARTICLE FOR CLEAN ROOM AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2006/025294
Kind Code:
A1
Abstract:
Disclosed is a molded article for clean rooms which is made of a resin composition obtained by melt-mixing 100 parts by weight of a cyclic olefin polymer (A) having a glass transition temperature of 60-200&ring C, 1-150 parts by weight of a soft copolymer (B) having a glass transition temperature of not more than 0&ring C and obtained by polymerizing two or more monomers selected from the group consisting of olefins, dienes and aromatic vinyl hydrocarbons, 0.001-1 part by weight of a radical initiator (C), and 0-1 part by weight of a multifunctional compound (D) having two or more radically polymerizable functional groups in a molecule. Such a molded article for clean rooms is excellent in chemical resistance, heat resistance and dimensional accuracy, and is suppressed in volatile component discharge to the environment. In addition, since the molded article is excellent in wear resistance, generation of particles can be suppressed.
