Polyolefin-based molded product coated with polar polymer, method for producing the same, and uses of the same

Abstract

A polyolefin-based molded product having excellent printability, coatability, heat resistance, impact resistance, hydrophilicity or hydrophobicity, or exhibiting excellent performance such as the performance of adhesion with metal, plastics, paper and the like, that is, a polyolefin-based molded product which is coated with a polar segment layer through covalent bonding, without impairing the properties of the polyolefin base material and without substantial delamination at the interface, based on a novel conception that a polyolefin molded product has a structure of being coated with polar polymer segments at the surface, and a vinylic monomer or a small-membered cyclic compound is polymerized on the surface; and a method for producing the same are provided. A polyolefin-based molded product having a polar polymer (B) coated on the surface of a polyolefin molded product (A), characterized by having a structure in which the polar polymer (B) is bound to the surface of the polyolefin molded product (A) through covalent bonding, and a method for producing the same are provided.
