Structure and properties of impact modified polyethylene terephthalate

摘要: In this paper, we investigate the orientation behavior of impact modified PET. Core-shell particles, a metallocene polyethylene (mPE) and glycidyl methacrylate mPE (gmPE) were blended with PET using single screw extrusion. Morphology, crystallinity, development mechanical properties oriented blends studied following different conditions. It was observed that core-shell modifier added to does not affectits particles do deform. Non-reactive mixing affect developed in for same draw ratio, but stress levels are affected (higher) due an earlier crystallization Reactive blending gmPE enhances when orienting higher than pure PET, strain hardening being oriented, which indicate good adhesion at interface. The elongation break is positively many cases addition modifier, particularly gmPE, indication improved toughness.
