摘要：
Soft polyolefin composition with improved processability comprising from 8 to 45% by weight of a polypropylene component (A), from 82 to 45% by weight of an elastomeric component (B), and from 10 to 25% by weight of a viscosity reducing agent (C) comprising polybutene-1 and paraffinic wax or grease. The composition is easily processable also by injection molding and has better tensile properties than compositions in which processability is improved by visbreaking.
