Title:
PRODUCTION OF VINYL CHLORIDE COPOLYMER
Document Type and Number:
Japanese Patent JPH02269709
Kind Code:
A
Abstract:
PURPOSE:To produce a vinyl chloride copolymer excellent in heat resistance, impact resistance and moldability by copolymerizing a vinyl chloride monomer with a cycloalkyl fumarate. CONSTITUTION:A vinyl chloride copolymer is produced by copolymerizing 99-1wt.% vinyl chloride monomer (A) with 1-99wt.% cycloalkyl fumarate (B) of the formula (wherein R<1> and R<2> are each H or a 3-12C cycloalkyl, and at least either of them is a 3-12C cycloalkyl), e.g. monocyclohexyl fumarate or dicyclohexyl fumarate. The obtained copolymer has a good balance between thermal property and mechanical property, is remarkably improved in heat resistance, impact resistance and moldability as compared with a conventional vinyl chloride resin, and is useful as the materials for piping materials, valves, automobile members, pipes, films, sheets, weak-current machine members, etc., which have been problematic in heat resistance, impact resistance and moldability.
