Abstract: The present invention relates to a propylene copolymer composition comprising (A) from 50.0 to 95.0 wt %, based on the total amount of the propylene copolymer composition, of a heterophasic propylene copolymer having a matrix phase and an elastomeric phase dispersed in said matrix phase, wherein the matrix phase is a propylene random copolymer, the heterophasic propylene copolymer further having a melt flow rate MFR2 of 0.2 to 12.0 g/10 min, determined according to ISO 1133 at a temperature of 230° C. and a load of 2.16 kg, and a xylene cold solubles (XCS) fraction in the range of from 20.0 to 50.0 wt % based on the total amount of the heterophasic propylene copolymer (A), determined according to ISO 16152 at a temperature of 25° C., and (B) from 5.0 to 25.

Abstract: A propylene copolymer composition is provided, wherein the composition includes from 50.0 to 90.0 wt %, based on the total amount of the propylene copolymer composition, of a heterophasic propylene copolymer having a matrix phase and an elastomeric phase dispersed in said matrix phase, wherein the matrix phase is a propylene random copolymer. The composition also includes from 5.0 to 25.0 wt %, based on the total amount of the propylene copolymer composition, of a propylene based plastomer from 5.0 to 25.0 wt %, based on the total amount of the propylene copolymer composition, of an ethylene based plastomer. An article comprising said propylene copolymer composition and the use of said propylene copolymer composition in a single ply roofing membrane is also provided.

Abstract: A process for increasing MFR2 of a polyethylene copolymer or an ethylene plastomer or elastomer comprising: (I) extruding a copolymer of polyethylene copolymer having a density of 910 to 970 kg/m3 and an MFR2 of 1 and 100 g/10 min or an ethylene plastomer or elastomer having a density of 855 to 910 kg/m3 and an MFR2 of 0.5 and 100 g/10 min in the presence of 0.1 to 2 wt % of a non-peroxide radical initiator so as to produce a polyethylene copolymer having an MFR2 of 200 g/10 min or more, or an ethylene plastomer or elastomer having a MFR2 of 200 g/10 min or more.

Abstract: In a one step process a body of woodchips or lignocellulosic fibres impregnated with a heat curable polar resin adhesive is contacted with EP(D)M rubber sheet containing peroxide curative and subjected to hot pressing. The rubber is thereby cured and caused to convulcanize and adhere to the woodchips to produce a weather resistant construction element.
