Abstract: A polymer composition and a process for the production of this composition comprising a base resin is disclosed herein. The base resin includes a very high molecular weight component, a low molecular weight component, and a high molecular weight component having a weight average molecular weight higher than the weight average molecular weight of the low molecular weight component but lower than the weight average molecular weight of the very high molecular weight component. An amount of the very high molecular weight component in the base resin is 0.5 to 8 wt %. The very high molecular weight component has a viscosity average molecular weight of greater than 1100 kg/mol. The composition has FRR21/5 of equal to or greater than 38, a melt flow rate MFR21 of equal to or greater than 6.5 g/10 min and a viscosity at a shear stress of 747 Pa (eta747) of 450 to 3000 kPas.

Abstract: The present invention relates to an adhesive composition comprising a. a polyethylene resin (A) which has been grafted with an acid grafting agent and b. an epoxy resin (B) in an amount of 0.01 to 15 wt. % of the adhesive total composition, wherein the adhesive composition is having a MFR5 of 0.1 to 12 g/10 min. Furthermore, the invention relates to an article, in particular a multilayer pipe, comprising an adhesive layer which comprises said adhesive composition and the use of said adhesive composition for the production of an adhesive layer, in particular of an adhesive layer of a pipe.
