MODIFIED PROPYLENE POLYMER

摘要

A modified propylene polymer having exceedingly superior coloring-preventive property is provided according to a process which comprises blending a specified phenolic antioxidant, a polyol or a fatty acid partial ester of the polyol, and a radical generating agent with a propylene polymer containing 5 ppm or more of titanium portion or 0.5 ppm or more of vanadium portion of catalyst residue and subjecting the resultant blend to the melting and kneading treatment at a temperature of l50 DEG C - 300 DEG C.
