OLEFIN/AROMATIC VINYL COPOLYMER, PROCESS FOR PRODUCTION THEREOF, RESIN COMPOSITIONS CONTAINING THE COPOLYMER, AND STRETCHED PRODUCTS OF THE COPOLYMER |
摘要 |
<p>The present invention relates to such a copolymer comprising an olefin and an aromatic vinyl compound that has a syndiotactic structure, high block property and a wide molecular weight distribution. Specifically, it relates to a copolymer comprising an olefin and an aromatic vinyl compound, in which a content of the aromatic vinyl compound is from 1 to 99% by mol; a molecular distribution is 1.7 or more; a signal based on an (olefin-aromatic vinyl compound-olefin) linkage as a node of the copolymer, a signal based on an (aromatic vinyl compound-aromatic vinyl compound-olefin) linkage, a signal based on an (aromatic vinyl compound-aromatic vinyl compound-aromatic vinyl compound) linkage as a block linkage of the aromatic vinyl compound, and a signal based on an (olefin-olefin-olefin) linkage as a block linkage of the olefin are present; an index showing block property of the aromatic vinyl compound component is from 30 to 100%; and a stereoregularity of a repeating unit chain constituted by the aromatic vinyl compound is 80% by mol or more, a method for producing the same, a resin composition, and a stretched product.</p> |
