Abstract

A polyolefin composition and a molded article obtained therefrom are disclosed. The composition comprises a polyolefin and a modified polymer obtained by graft-copolymerizing an unsaturated dicarboxylic acid or an anhydride thereof to a specific ethylene-propylene-based copolymer rubber. The molded article obtained from the composition has an increased impact strength and improved workability in finishing, particularly coating with an urethane coating.
