PET/Mica nanocomposites for food packaging: crystallization behavior and mechanical properties [PDF]

Journal of Food and Bioprocess Engineering, 2018
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)

Modeling of Poly(Ethylene Terephthalate) Homogeneous Glycolysis Kinetics

, 2023
Polymer composites with various recycled poly(ethylene terephthalate)-based (PET-based) polyester matrices (poly(ethylene terephthalate), copolyesters, and unsaturated polyester resins), similar in properties to the primary ones, can be obtained based on

Poly(Ethylene Terephthalate): Synthesis and physicochemical properties

, 2017
This chapter summarizes the synthesis and physicochemical properties of thermoplastic polyester, poly(ethylene terephthalate) (PET). PET, along with poly(butylene terephthalate) (PBT) is an aliphaticaromatic and semicrystalline thermoplastic polyester of

A Perspective on PEF Synthesis, Properties, and End-Life

Frontiers in Chemistry, 2020
This critical review considers the extensive research and development dedicated, in the last years, to a single polymer, the poly(ethylene 2,5-furandicarboxylate), usually simply referred to as PEF.

On the modelling of highly elastic flows of amorphous thermoplastics [PDF]

, 2009
Two approaches to the kinematic structuring of constitutive models for highly elastic flows of polymer melts have been examined systematically, assuming either: (1) additivity of elastic and viscous velocity gradients or (2) multiplicability of elastic ...

Study on micro-phase separation structure of poly(ethylene terephthalate)-poly(hexylene terephthalate) (PET-PCT) copolymer [PDF]

e-Polymers, 2010
Abstract PET-PCT copolyesters were prepared from terephthalic acid (PTA), ethylene glycol (EG) and 1,4-cyclohexane dimethanol (CHDM) through direct esterification and the subsequent polycondensation. The chemical composition and sequence length distribution of the copolyesters were investigated by 1H-NMR and 13C-NMR.

Structural insight into catalytic mechanism of PET hydrolase

Nature Communications, 2017
Poly-ethylene terephthalate (PET) is a widely used plastic which accumulates in the environment with detrimental consequences. Here the authors report crystal structures of a PET-hydrolyzing enzyme from the microbe Ideonella sakaiensis bound to substrate

Interactions of PP-PET blends modified by montmorillonite with different polarities

Polímeros, 2022
This paper describes the effects of adding organic montmorillonite clays (MMT) with different polarities (one polar and one non-polar) in recycled poly (ethylene terephthalate) (PET) and polypropylene (PP) blends. Styrene-Ethylene/Butylene-Styrene-maleic
