POLYOLEFIN COMPOSITIONS AND FILMS OBTAINED THEREFROM

摘要

Polyolefin compositions comprising from 70 to 99 parts by weight of a composition (A) comprising: (i) from 75 to 95 % by weight of a copolymer of ethylene with an .alpha.-olefin CH2=CHR, wherein R is an alkyl radical having from 1 to 10 carbon atoms; and (ii) from 5 to 25 % by weight of a copolymer of propylene with ethylene and/or an .alpha.-olefin CH2=CHR1, wherein R1 is an alkyl radical having from 2 to 10 carbon atoms and from 1 to 30 parts by weight of a polyolefin component (B) comprising crystalline polybutene-1. The polyolefin compositions of the invention are endowed with an improved processability while the films obtained therefrom show improved mechanical properties with respect to those of the prior art.
