摘要： The present invention relates to an adhesive polyethylene composition comprising (A) from 60 to 90 wt % of a non-elastomeric polyethylene being a terpolymer of ethylene with two different alpha-olefin comonomer units selected from alpha-olefins having from 4 to 12 carbon atoms; (B) from 9.0 to 38 wt % of an elastomer; wherein onto component (A) or components (A) and (B) an acid grafting agent (C) has been grafted in an amount of from 0.01 to 3.0 wt %, all based on the total weight of the adhesive polyethylene composition, a multi-layer structure comprising said adhesive polyethylene composition and the use of said adhesive polyethylene composition for the production of a multi-layer structure.

摘要： Articles comprising a polymer composition, wherein the polymer composition is obtainable by grafting an ethylene copolymer with comonomer units comprising hydrolysable silane groups, wherein the polymer composition shows high gel content and low compression set at −25° C. These articles have applications in automotive weather-stripping, such as sealing systems for doors, trunks and hoods.

摘要： The invention relates to a polypropylene composition (C) comprising: (i) 62 to 85 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO1) with a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 6.0 to 50.0 g/10 min; (ii) 10 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of a heterophasic propylene copolymer (HECO2) with a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 0.1 to 5.5 g/10 min; (iii) 5 to 30 wt.-%, based on the total weight of the polypropylene composition (C), of an inorganic filler (F); wherein (a) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower amount [in mol %] of C2 and/or C4 to C12 α-olefin derived comonomer units than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); (b) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO1) has a lower the intrinsic viscosity (IV) than the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2); and (c) the xylene cold soluble (XCS) fraction of the heterophasic propylene copolymer (HECO2) has an intrinsic viscosity (IV) in the range of 6.0 to 15.0 dl/g.

摘要： The present invention provides a process of producing a modified polymer composition, which composition comprises a free-radical polymeriseable monomer grafted to a polyolefin backbone. The process comprises contacting, in an extruder, an olefin polymer and the free-radical polymeriseable monomer in the presence of a stable radical in an extruder and extruding the composition.

摘要： A process for polymerizing ethylene in the presence of a polymerization catalyst by copolymerizing ethylene with a comonomer selected from the group of C4-C10 alpha-olefins in three polymerization stages. The polymers produced in the three stages have different melt flow rates. The polymer composition produced by the process has good mechanical properties and can be used for making pipes. The process has a good productivity and provides a stable and economic operation.
