PROCESS FOR LOWERING THE MELT FLOW RATE OF A RECYCLED POLYMER COMPOSITION

PROCESS FOR LOWERING THE MELT FLOW RATE OF A RECYCLED POLYMER COMPOSITION

A process for lowering the melt flow rate of a recycled polymer composition comprising at least 50 wt% of a recycled polypropylene composition and comprising at least 5 wt% of a polar polymer comprising:a) providing a recycled polymer composition;b) adding to the composition from 2 wt% to 10 wt% bas...

description A process for lowering the melt flow rate of a recycled polymer composition comprising at least 50 wt% of a recycled polypropylene composition and comprising at least 5 wt% of a polar polymer comprising:a) providing a recycled polymer composition;b) adding to the composition from 2 wt% to 10 wt% based on the weight of the total composition an ethylene-alfa-olefin copolymer or ethylene-alfa-olefin terpolymer grafted with maleic anhydride.c) melting the composition comprising component a) and b) andd) recover the final polymer.
