PURPOSE:To provide an extrusion molded article made from a specific olefin polymer which can be extruded at a high rate into a large size. CONSTITUTION:An extrusion molded article is made from an olefin polymer contg. an alpha-olefin-polyene copolymer. The olefin polymer is prepd. by copolymerizing an alpha-olefin with a polyene in the presence of a catalyst system comprising a transition metal compd. catalyst component and an organometallic compd. catalyst component contg. a metal selected from the group consisting of metals of the groups I, II, and III in an amt. of the sum of the alpha-olefin and the polyene of 0.01-2,000g based on 1g of the transition metal compd. catalyst component and (co)polymerizing an olefin in the presence of the resulting catalyst system contg. an alpha-olefin-polyene copolymer. |
