Abstract:
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.
