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 positron lifetime study of structural relaxation in UV irradiated poly (ethylene terephthalate)

, 2002
Structural relaxation in UV irradiated poly (ethylene terephthalate) (PET-UV) has been investigated using positron lifetime techniques. Positron lifetime results show that the structural relaxation processes in PET-UV encompass three different time ...

Effects of Polyamide‐6 Bulk Plasma Treatment on Morphology, Crystallinity and Mechanical Properties of Microfibrillar Composites

Polymer Composites, Volume 47, Issue S2, Page S261-S274, 20 June 2026.
Microfibrillar composite containing highly oriented, plasma‐treated PA6 microfibrils embedded within the polymer matrix. ABSTRACT Plasma treatment is often used to alter chemical surface characteristics of fibers or polymers, improving dispersion of components and interfacial adhesion between incompatible constituents in composites.

Morphological changes of poly(ethylene terephthalate) on multiple steam sterilization.

, 1990
Poly(ethylene terephthalate) (PET) was steam sterilized by autoclaving for 15, 30 and 60 min. The thermal properties, T m, delta-H and percent crystallinity were determined using differential scanning calorimetry.

Application of poly(ethylene terephthalate)-graft-polystyrene membranes in pervaporation

, 2006
Gamma radiation-induced grafting of styrene (ST) onto poly(ethylene terephthalate) (PET) films was used to prepare poly(ethylene terephtalate)/polystyrene (PET-g-PST) membranes having various degrees of grafting.
