This article presents the results of studies on the effect of the erbium chelate complex on the processing of secondary raw materials from polyethylene terephthalate (PET).

Keywords: polyethylene terephthalate, recycling, extrusion, polyisobutylene, chelate complex of erbium.

The article examines the effect of polytitanate potassium intercalated copper on the structure and physico-mechanical properties of composite materials containing as a filler. Matrix composite material is a mixture of polyethylene 277 and copper-polymer complex of polyacrylamide. It is shown that the pre-intercalation of polytitanate potassium copper improve of physico-mechanical properties of the composite material.

Keywords: intercalated, polytitanate potassium, polyethylene, copper-polymer complex of polyacrylamide, friction coefficient, wear resistance, structure, hardness, elemental composition

In the article methods of utilization of PET. The chemical method chosen by us is one the most priority types of the processing of plastic containers (bottles - PET). Also results of some physical and mechanical tests of the modified PET

Keywords: PET, chemical modification, polyisobutylene, recycling, extrusion
