Molded product comprising polarized olefin-based polymer and property thereof

An olefin-based molded product comprising a polymer comprising a structural unit of at least one polar olefin monomer represented by the general formula (II):

• wherein, Z is a hetero atom selected from the group consisting of nitrogen, oxygen, phosphorus, sulfur, and selenium;
• R1 is 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;
• R3 is a hydrocarbylene group having 1 to 5 carbon atoms;
• R4 is a halogen atom, a hydrocarbyl group having 1 to 10 carbon atoms, an alkylthio group having 1 to 10 carbon atoms, an alkylamino group having 1 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms, and when R4 is a hydrocarbyl group, the hydrocarbyl groups may bond together to form a condensed ring;
• and m is an integer of 0 to 4,
• wherein the proportion of the polar olefin structural unit in the total structural units in the polymer is 20 mol % or more.
