摘要：The present invention relates to such a copolymer comprising an olefin and anaromatic vinyl compound that has a syndiotactic structure, high block property and awide molecular weight distribution. Specifically, it relates to a copolymer comprising anolefin and an aromatic vinyl compound, in which a content of the aromatic vinyl compoundis 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 signalbased on an (aromatic vinyl compound-aromatic vinyl compound-olefin) linkage, a signalbased on an (aromatic vinyl compound-aromatic vinyl compound-aromatic vinyl

compound) linkage as a block linkage of the aromatic vinyl compound, and a signal basedon an (olefin-olefin-olefin) linkage as a block linkage of the olefin are present; an indexshowing 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.
