COMPOSITIONS BASED ON PROPYLENE COPOLYMERS HAVING STATISTICAL DISTRIBUTION OF MONOMER LINKS, METHOD FOR THEIR PREPARATION AND THERMORESISTANT MULTILAYER FOIL BASED ON THESE COMPOSITIONS

摘要

The invention relates to compositions based on propylene polymers (C compositions) including from 68 to 80 wt.% propylene compolymer having statistical monomer links distribution (copolymer A) containing from 12 to 20 wt.% of the derivative units of 1-butene and 0-2 wt.% of the derivative units of ethylene, and from 20 to 32 wt.% propylene copolymer having statistical monomer links distribution (copolymer B) containing from 0 to 15 wt.% of the derivative units of 1-butene and from 1 to 8 wt.% of the derivative units of the ethylene. 13 claims
