Use of a Graft Copolymer of Low Molecular Weight Polyethylene and Acrylic Acid in Carbon Black-Filled Polyethylene Compouns

Composites based on carbon black/high-density polyethylene composites and, as well as linear low-density polyethylene containing graft copolymers of low molecular weight polyethylene and acrylic acid, have been produced. The introduction of graft copolymers into the polyethylene matrix helps to reduce the average size of carbon black particles in the composition, reduce the melt viscosity and improve the thermal stability of carbon black-filled compositions, which is important for the production of pipe products based on polyethylene.
