Investigation of a Polyamide 6 (PA6) and Polybutylene Succinate (PBS) Blend as Candidate Matrix for Self‐Healing Application

Polymer Engineering &Science, EarlyView.
This illustration shows polyamide 6 (PA6) blended with 20–50% polybutylene succinate (PBS) by volume. The balance between tensile properties, fracture toughness and self‐healing capability is achieved in the 30% vol PBS blend. Thermal healing at 140°C results in 40% fracture toughness recovery in a blend containing 30% vol PBS.

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.

Extruder‐based 3D printing of eco‐friendly polymers

Polymer International, EarlyView.
Eco‐friendly polymers, such as biodegradable and recycled materials, offer significant potential for the production of high‐quality 3D‐printed components, provided that their properties and characteristics meet the requirements of extruder‐based 3D printing.

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.

Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

Journal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,
