Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Olefin Polymerizations Oriented by Rational Designs of Group‐13 Compounds

The Chemical Record, EarlyView.
In coordination olefin polymerization chemistry, boron and aluminum compounds play important roles in both catalyst components and monomers. This personal account introduces our recent progress on the development of catalyst systems featured by the design of group‐13 counteranions, as well as the application of boronic acid‐crosslinked polyolefins to ...

Influence of external nitrogen-containing donors on polymerization behavior of neodymium-based cis-1,4-polybutadiene rubber

Hecheng xiangjiao gongye
"Neodymium(Nd)-based catalyst in butadiene (Bd) polymerization has drawn interests due to its availability in affording higher cis-1,4-unit selectivity than transition metal (Ti, Co, Ni, etc.)-based catalysts［1-2］.

Synthesis and Evaluation of Novel Thermoplastic Elastomers via Anionic Polymerization of Bio‐Based α‐Methyl‐p‐Methylstyrene

Journal of Polymer Science, Volume 64, Issue 3, Page 743-751, 1 February 2026.
Bio‐based PAMMS‐PI‐PAMMS triblock copolymers prepared via sequential anionic polymerization display widely tunable tensile behavior. Variation of the block composition enables systematic control of strength and extensibility, offering a sustainable platform for thermoplastic elastomers. ABSTRACT In this study, we examined novel thermoplastic elastomers

Controlled synthesis of neodymium-based cis-1,4-polybutadiene rubber bearing polystyrene microblock

Hecheng xiangjiao gongye
A series of neodymium-based cis-1,4-polybutadiene rubbers bearing polystyrene microblocks were prepared by adding styrene monomer in aging stage of neodymium-based catalyst, the effects of different styrene amount on the polyme-rization behavior and ...

Optimizing Epoxy Vitrimer Composites With Sustainable Cellulose Nanofibril Reinforcements: Enhancing Thermal Dimensional Stability While Preserving Dynamic Covalent Behavior

Polymer Composites, Volume 47, Issue 1, Page 164-175, 10 January 2026.
A vitrimer nanocomposite based on nanofibrillated cellulose was fabricated using controlled resin infiltration, without the need for any functionalization. It exhibited excellent thermal dimensional stability and recyclability, positioning it as a promising material for next‐generation, eco‐responsible composites and protective coating aligned with ...

Structural and Dynamic Origins of Payne Effect Reduction by Steric Stabilization in Silica Reinforced Poly(butadiene) Nanocomposites

Polymer Composites, Volume 47, Issue 1, Page 532-542, 10 January 2026.
Steric stabilisation of silica nanoparticles suppresses the Payne effect in poly(butadiene) nanocomposites and enables the thickness of the glassy layer to be quantified with QENS experiments. ABSTRACT Silica nanoparticles in polybutadiene nanocomposites cause significantly hindered polymer dynamics in the form of a glassy layer, which can extend more ...

Rheological Characterization of Low and High‐Solids‐Loaded Suspensions Using Capillary Rheometry

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 1, Page 144-156, January 2026.
ABSTRACT Controlled extrusion of viscous liquids with suspended solids depends critically on rheology. The rheology of a binder (9:1 mass ratio of cellulose acetate butyrate (CAB) to triacetin with a 55 wt.% diethyl ketone balance) loaded with dilute (0–15 wt.%) and concentrated (≥50 wt.%) granulated sugar loadings from three particle size ...
