Abstract: The invention relates to long-chain branched polypropylene composition (b-PPC) comprising at least one long-chain branched propylene homopolymer or copolymer (b-PP) and at least one linear propylene homopolymer or copolymer (l-PP). The long-chain branched polypropylene composition (b-PPC) being suitable for foam application.

Abstract: The invention relates to a process for the production of a foam having low organic compounds emissions, to polypropylene foamed products obtainable by the process, and to a process for the manufacture of low organic compounds emission articles comprising a foam for use in cars and food packaging. The process comprises the steps of: a) providing a foam comprising a propylene composition comprising a high melt strength propylene (HMS-PP) homopolymer or copolymer or combinations thereof, said HMS-PP foam having a melt strength of at least 25 cN at a maximum speed of at least 200 mm/s and a melting temperature of at least 135° C. and b) subjecting the HMS-PP foam to a thermal treatment at a temperature Tt which is preferably between 5 and 15° C. below the melting temperature Tm of the HMS-PP for a duration between preferably 1 and 10 minutes.

Abstract: The invention relates to long-chain branched polypropylene composition (b-PPC) comprising at least one long-chain branched propylene homopolymer or copolymer (b-PP) and at least one linear propylene homopolymer or copolymer (1-PP). The long-chain branched polypropylene composition (b-PPC) being suitable for foam application.

Abstract: The invention relates to propylene polymer blends comprising 70-92 wt % of a propylene homopolymer, 5-15 wt % of an elastomeric ethylene-propylene copolymer, 3-15 wt % of a linear low density polyethylene and an a-nucleating agent. The propylene polymer blends have an excellent impact strength/stiffness balance and optical properties. They are especially suitable for thermoforming and extrusion blow moulding.
