PRODUCTION OF MOLDED PRODUCT OF CROSSLINKED POLYOLEFIN

摘要

PURPOSE:To produce a molded product of a crosslinked syndiotactic polyolefin excellent in solvent resistance. CONSTITUTION:A mixture comprising a copolymer of a syndiotactic allylsilane with an olefin and a copolymer of ethylene and propylene with an alkadiene is molten by heating and molded to form a molded piece wherein no peak of tandelta assignable to the copolymer of ethylene and propylene with the alkadiene is observed by analysis of dynamic viscoelasticity. The molded piece is then brought into contact with a catalyst to produce a molded product of a crosslinked polyolefin.
