In Situ Reactive Interfacial Compatibilization of Poly(Ethylene Terephthalate)/Metallocene Polyethylene Blends

Abstract:

Poly (ethylene terephthalate) (PET) was melt blended with metallocene polyethylene (m-PE) with an effort to achieve excellent mechanical properties, a terpolymer elastomer, ethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA), was loaded as compatibilizer through in situ reacting with the end groups of PET to bond two immiscible phases. In order to investigate the in situ effects of the compatibilizer, scanning electron microscopy (SEM) and mechanical analysis was applied to investigate PET/m-PE blends’ properties along with the variation of compatibilizer content. Statistics of particle size were applied to demonstrate the variation of the blends’ properties along with morphology. The results revealed that an appropriate loading of compatibilizer can obtain stiffness-toughness balanced blends.
