    摘要： The present invention relates to a polymer composition comprising (A) from 60 to 90 wt % of a non-elastomeric polyethylene; (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 polymer composition, and wherein the polymer composition has two distinct peaks and a valley between said peaks in the GPC curve and a Z value, determined from the areas below the two peaks of the GPC curve, of at least −0.3, wherein the Z-value is determined according to formula (I) Z=s/Abs(B−A) (I) wherein Abs(B−A) is the absolute value of (B−A); A=the area, between the tangent parallel to the MW axis going through log M (Min) and the LS15 signal, from log M of 5.1 to log M value where the LS signal is minimum log M (Min), in the log M range between 5.1 and 6; B=the area, between the tangent parallel to the MW axis going through log M (Min) and the LS 15 signal, from log M(Min) to the point where the LS signal is crossed again; and s is the slope between the two peaks of the GPC curve, defined at log M of 5.1 and 6, wherein the GPC curve is defined as the concentration normalized LS 15 signal along the molecular weight of conventional GPC, obtained from the GPC-VISC-LS analysis, a multi-layer structure such as a coated metal pipe, comprising one layer comprising said polymer composition and the use of said polymer composition as adhesive polymer composition and for the production of a multi-layer structure.

    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： Polymer composition comprising at least one polypropylene homopolymer and/or random copolymer, up to 15 wt % of at least one polyethylene, optionally at least one elastomer in an amount of 8 to 40 wt % and optionally fillers and/or additives in an amount of up to 45 wt % based on the total weight of the final polymer composition with the at least one polyethylene having a density of higher than 940 kg/m3, a content of hexane hot extractables of below 0.80 wt % preferably below 0.60 wt %, most preferably below 0.40 wt % and a copolymer/homopolymer (COHO) ratio measured by Temperature Rising Elution Fraction (TREF) up to 6%.
