PROCESSING AID FOR POLAR POLYMERS

摘要

Segmented copolymers of polyolefins with relatively high molecular weight poly(methacrylate) segments, known to be useful as melt strength additives for polyolefins and compatibilizers for blends of polyolefins and polar polymers, are now found to be useful at levels of about 1 to about 15 weight percent in improving the processing properties of polar polymers, such as by decreasing the time for PVC to flux, by decreasing the temperature and pressure requirements for injection molding, and by improving the melt strength of ABS.
