FILM OF POLYMER MIXTURE CONTAINING 4-METHYL-1-PENTENE POLYMER |
摘要 |
<p>A film composed substantially of a polymer mixture containing a 4-methyl-1-pentene polymer, said polymer mixture comprising (A) the 4-methyl-1-pentene polymer and (B) a copolymer of propylene and an alpha-olefin, the propylene/alpha-olefin copolymer (B) containing 40 to 87 mole% of the propylene component and a heat of crystal fusion of not more than 80 joules/g, and the content of the propylene/alpha-olefin copolymer (B) being 5 to 70% by weight based on the total weight of the 4-methyl-1-pentene polymer (A) and the propylene/alpha-olefin copolymer (B).</p> |
