The object of the invention is to provide a novel olefin-based molded product useful for various applications. An olefin-based molded product comprising a polymer including a structural unit of at least one polar olefin monomer represented by the general formula (I) CH═CH—R—Z(R)is provided. In the formula, Z is a hetero atom selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur, and selenium; Ris a substituted or unsubstituted hydrocarbyl group having 1 to 30 carbon atoms; n is an integer of 1 or 2 depending on the atomic species of Z; and Ris a substituted or unsubstituted hydrocarbylene group having 2 to 20 carbon atoms.

Molded product comprising polarized olefin-based polymer and property thereof

An object of the present invention is to provide a novel method of producing a nonpolar olefin polymer (e.g., a copolymer of a nonpolar olefin and a polar olefin). The present invention provides a method of producing a polar olefin polymer or copolymer, the method including the polymerization step of polymerizing a polar olefin monomer using, as a catalyst, a polymerization catalyst composition containing: 1) a metallocene complex represented by Formula (I), which contains a central metal M that is scandium (Sc) or yttrium (Y), a ligand Cp* containing a cyclopentadienyl derivative and being bound to the central metal, monoanionic ligands Qand Q, and W neutral Lewis bases L wherein W is an integer of 0 to 3; and 2) an ionic compound composed of a non-coordinating anion and a cation.
