Microwave‐assisted depolymerization of poly(ethylene terephthalate) [PET] at atmospheric pressure

Advances in Polymer Technology, 2006
AbstractMicrowave‐assisted hydroglycolysis of poly(ethylene terephthalate) using an excess of methanol, ethanol, 1‐butanol, 1‐pentanol, and 1‐hexanol in the presence of different simple basic catalysts, namely, potassium hydroxide, sodium hydroxide, sodium acetate, and zinc acetate, is reported.

Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

Polymer Composites, EarlyView.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Impact of Waste‐Derived Slate Dust on Structural, Thermal, and Thermomechanical Behavior of Recycled Poly(Ethylene Terephthalate)

Polymer Composites, EarlyView.
This study investigates the use of waste slate dust as a filler in recycled PET. Incorporating up to 20 wt% slate dust caused no filler‐induced molecular degradation, increased the crystallization temperature, thermal conductivity, and storage modulus. ABSTRACT Recycled polyethylene terephthalate (rPET) is widely considered a sustainable alternative to

Enhancing PET Printability via Solid‐State Polymerization: Structure‐Processing‐Properties Relationships

Polymer Engineering &Science, EarlyView.
Solid‐state polymerization (SSP) enhances rheological properties, filament stability, and adjusts crystallization issues for improved PET 3D printability. ABSTRACT This paper aims to investigate the impact of solid‐state polymerization (SSP) on the printability of PET for 3D printing.

Depolymerization mechanisms and closed-loop assessment in polyester waste recycling

Nature Communications
Alcoholysis of poly(ethylene terephthalate) (PET) waste to produce monomers, including methanolysis to yield dimethyl terephthalate (DMT) and glycolysis to generate bis-2-hydroxyethyl terephthalate (BHET), is a promising strategy in PET waste management.

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.
