POLYOLEFIN RESIN COMPOSITION

摘要

PURPOSE: To obtain a polyolefin resin compsn. capable of realizing long-term thermal stabilization of a polyolefin resin by maintaining a high concn. of an anti-oxidizing agent in the polyolefin resin. CONSTITUTION: A polyolefin resin compsn. comprises 100 pts.wt. polyolefin resin, 0.5-5 pts.wt. porous material having an average particle size of l to 100μm and a porosity of 30 to 90% as measured with a mercury intrusion type porosimeter, and an anti-oxidizing agent blended therein in a state of being borne on the porous material.
