Abstract

Technology of processing the industrial wastes from the production of linear polyethylene obtained through the liquid-phase polymerization technology in the presence of Ziegler-Natta catalysts was developed. The technology implies separation of wastes by centrifuging and simple distillation centrifugate leading to the low molecular mass polyethylene, low-boiling hydrocarbon fraction (130–210 °C) and the bottoms. The major technological characteristics and application areas for the products of waste processing were established.
