Modified propylene polymer composition and process of making composition |
摘要 |
A modified propylene polymer having superior coloring-prevention properties is provided by a process which comprises blending a propylene polymer with (A) a polyol or a fatty acid partial ester of the polyol (B) a phenolic antioxidant and (C) a radical generating agent with a propylene polymer containing 5 ppm or more of titanium or 0.5 ppm or more of vanadium as a catalyst residue and subjecting the resultant blend to a melting and kneading treatment at a temperature of 150 DEG C.-300 DEG C.
