POLYETHER COPOLYMER AND ITS CROSSLINKED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a polyether copolymer usable as a rubber having any of excellent heat resistance, oil resistance, fuel oil resistance, low temperature characteristics and semiconducting characteristics either with use of only a small amount of a halogen-containing compound or with disuse at all thereof, and to provide its crosslinked product. SOLUTION: The polyether copolymer consists of (a) 6-69 mol% of a phenyl glycidyl ether unit, (b) 30-90 mol% of an alkylene oxide unit selected from among ethylene oxide, propylene oxide, isobutylene oxide and n-butylene oxide, and (c) 1-10 mol% of a crosslinkable oxirane monomer unit, and its Mooney viscosity (ML1+4) measured at 100°C is in the range of 10-200. Also provided is the crosslinked product obtained by crosslinking the copolymer. COPYRIGHT: (C)2005,JPO&NCIPI
