Compatibilization, processing and properties of post-consumer PET/polyolefin blends

Abstract

The possibilities of poly(ethylene terephtalate) and polyolefins recycling by blending together are discussed. Two approaches are presented: use of commercial compatibilizer and formation of compatibilizer during blend preparation. It was found that for blends of recycled PET/PE-HD the most effective compatibilizer was EGMA, which improved the dispersion of the minor phase and the mechanical properties of a blend. Liquid lycidyl methacrylate in the amount 2-4 pph may be used as a omponent for reactive extrusion of PET/PE-HD, with formation f PE-HD-g-GMA during processing.
