RESEARCH ON THE TECHNOLOGY OF EXTRACTING LOW MOLECULAR WEIGHT POLYETHYLENE FROM PRODUCTION WASTE

Abstract

In the article, the synthesis of polymeric antioxidants based on local secondary raw materials was studied and applied in the stabilization of polyethylene. It is known that polyolefins have sufficiently high mechanical strength and dielectric stability, and are resistant to the effects of aggressive environments, acids, alkalis and salt solutions. Their disadvantage is poor adhesion, lack of polar groups, relatively low hardness, so these properties sometimes limit their use as construction materials. Unstabilized polyolefins lose many of their valuable properties during processing and aging during service and storage.
