to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...

nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. in this study pet nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. the morphology of pet/mica nanocomposites was characterized by x-ray diffraction and transmission electron mi...

Block copolymers composed of poly(trimethylene carbonate) and polylactide can be processed at ambient temperature under pressure by a reversible pressure-induced phase transition between an ordered (solid) state disordered (melt/solid) state.

Poly(ethlyene terephthalate) waste from a local market was depolymerized by ethylene glycol (EG) in the presence of Lewis acidic ionic liquids [Bmim]ZnCl3 and the qualitative analysis showed that bis(hydroxyethyl) terephthalate was the main product. Compared with ionic liquid [Bmim]Cl, the Lewis acidic ionic liquids showed highly catalytic activity in the glycolysis of poly(ethylene terephthala...
