Zusammenfassung: | The present invention relates to a polymer composition comprising at least the following components: A) 75 to 95.5 wt.-% based on the overall weight of the polymer composition of a polymer blend, comprising a1) polypropylene; a2) polyethylene; wherein the weight ratio of a1) to a2) is from 3:7 to 9:1; and wherein the polymer blend A) is a recycled material; (B) 4.5 to 25 wt.-% based on the overall weight of the polymer composition of a virgin ethylene alkyl (meth)acrylate having the following properties MFR2 (190°C, 2.16 kg) determined according to ISO 1133 in the range from 0.1 to 15 g/10 min; and an alkyl (meth)acrylate content based on the total weight of component B) in the range from 5 to 40 wt.-%; with the proviso that the weight proportions of components A) and B) add up to 100 wt.-%. Furthermore, the present invention relates to a process for manufacturing the polymer composition according to the present invention, to the use of component (B) for increasing the Tensile Strain at Break measured according to ISO527-2; and/or the Charpy Notched Impact Strength measured according to ISO 179-1eA at 23°C of a polymer blend A) of a recycled material comprising a1) polypropylene and a2) polyethylene in a weight ratio of a1) to a2) from 3:7 to 9:1 and to articles comprising the polymer composition. |
