Blends and reaction products prepared from phenolic resins and waste pet. I. Mechanical properties

Abstract

Blends or reaction products of novolac and resol type phenolic resins with waste poly(ethylene terephthalate) (PET) with up to 35% PET waste content, can after compression molding, yield composites with an interpenetrating network of phenolic matrix, supported by thermoplastic PET. Optimal amounts of waste PET improved the mechanical properties of the moldings, such as compression strength and hardness and, inmost cases, the strain to failure.
