PURPOSE:To carry out the crosslinking simply and easily in a short time and prevent the deformation of a molded article by crosslinking a copolymer of an alkenylsilane and an olefin in the presence of a hydrosilylation catalyst. CONSTITUTION:0.001-30mol% alkenylsilane and an olefin are copolymerized in the presence of a Ziegler-Natta catalyst comprising a transition metal catalyst and an organometallic compd. The resulting copolymer is crosslinked with 0.00001wt.% or higher (based on the olefin in the copolymer) hydrosilylation catalyst such as a triphenylphosphine complex of rhodium, a group VIII metal catalyst, e.g. chloroplatinic acid (salt), a radical initiator, e.g. an azo compd., and an amine, e.g. triethylamine. |
