Abstract

Disclosed is a polymer composition having a semi-homogeneous phase that exhibits excellent electrical, mechanical and thermal properties while satisfying flexibility, bendability and impact resistance. More specifically, disclosed is a polymer composition having a morphology in which a rubber-phase filler of a propylene copolymer is dispersed in a matrix of polypropylene, wherein an elution rate of the rubber-phase filler in a xylene-based solvent is less than 50%, based on the content of the rubber-phase filler such that the rubber-phase filler forms a semi-homogeneous phase with the matrix.
