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.

Polymer composition based on polypropylene/propylene copolymer having semi-homogeneous phase

Disclosed is an eco-friendly polymer composition for an insulation layer of power cables having a morphology in which a second phase substance of polypropylene composite is dispersed in a first phase substance of polypropylene, wherein the polypropylene composite of the second phase substance has a morphology in which an at least partially cured elastomer is dispersed as a filler in a matrix of polypropylene.
