Long-chain branched polypropylene for film application

摘要

The invention relates to a propylene homopolymer or copolymer having a comonomer in the copolymer selected from ethylene, C₄-C₂₀-alpha olefin, said propylene homopolymer or copolymer being free of phthalic compound. It further relates to a long-chain branched propylene homopolymer or copolymer (b-PP) having a comonomer in the copolymer selected from ethylene, C₄-C₂₀-alpha olefins, said long-chain branched propylene homopolymer or copolymer (b-PP) being free of phthalic compound. As well as their production processes and uses.
