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...

Thermal behaviour of blends of a liquid crystalline copoly(ester amide) (Vectra B950) with two isotropic polymers has been studied by differential scanning calorimetry. One of the isotropic polymers is an amorphous polymer — polycarbonate, the other is a semi-crystalline polymer — poly(ethylene terephthalate). It was found that the glass transition temperature of polycarbonate decreases with in...

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...

The Plastic Waste phenomenon, which is the result of increasing poly (ethylene terephthalate) production and the wide range PET consumption in different industries, caused one of the major environmental concerns. Therefore,many different ways have been studied and applied for chemical recycling of PET. One of the most important ways to depolymerize poly (ethylene terephthalate) is the aminolysi...

This work presents an experimental study on the interplay between structure and dynamics during isothermal cold crystallization of a copolymer based on poly(ethylene terephthalate) and poly(ethylene isophthalate) of poly(trimethylene terephthalate). Simultaneous X-ray scattering and dielectric spectroscopy measurements revealed that, during cold crystallization, crystalline lamellae tend form l...
