Patent ID: 8026309

Claim:
A process for providing a compatibilized polymeric blend composition, comprising: providing at least one polyethylene polymer, a reactive moiety, an optional initiator, and an optional catalyst to an upstream portion of a first progressive melt kneading apparatus, the reactive moiety comprising a first reactive group capable of reacting with the polyethylene polymer and a second reactive group capable of reacting with a polyamide polymer to be subsequently provided; melt kneading the polyethylene polymer and the reactive moiety so that the first reactive group reacts with the polyethylene polymer and grafts the second reactive group to at least one portion of the polyethylene polymer, thereby forming a molten self-compatibilizer; providing at least one molten polyamide polymer to the first progressive melt kneading apparatus; and melt kneading the molten self-compatibilizer with the polyamide polymer at a downstream portion of the first progressive melt kneading apparatus so that the second reactive group reacts with at least one portion of the molten polyamide polymer to form the compatibilized polymeric blend composition; and wherein the compatibilized polymeric blend composition comprises from 5 to 40 wt % of the polyamide polymer.
