POLYOLEFIN MIXTURE CONTAINING POLY(1-BUTENE)

摘要

PURPOSE: This invention concerns an elastomeric and thermoplastic polyolefin mixture. More particularly, it concerns a mixture comprising a heterophasic polyolefin composition and some crystalline or partially crystalline poly(l-butene), and the articles produced with the mixture. CONSTITUTION: Thermoplastic and elastomeric polyolefin mixture comprising from 3 to 25 % by weight of crystalline or partially crystalline isotactic poly(1-butene), and from 75 to 97 % by weight of a heterophasic polyolefin composition; the latter containing a crystalline propylene polymer and an elastomeric copolymer of ethylene with propylene and/or an alpha -olefin.
