Flow activation quantities of trimethylolpropane ester.

Journal of The Japan Petroleum Institute, 1982
The flow activation quantities of eight trimethylolpropane esters and two mixtures were experimentally determined at 313.2K. The relation between activation quantities and molecular structures of these esters was discussed. The activation quantities of the physical mixtures were compared with those of the corresponding "chemical" mixtures of the same ...

Recyclable and Degradable Covalent Adaptable Polymer Networks (CANs) Based on Dynamic Thiol–Yne Reactions

Journal of Applied Polymer Science, Volume 143, Issue 44, November 20, 2026.
Covalent adaptable networks based on activated alkynes, that is, alkynones, and multifunctional thiols (three and tetrafunctional) are tested in two different recycling strategies: (i) mechanical recycling based on their vitrimeric properties and (ii) chemical recycling based on the reversible thiol addition on the vinylene compound.

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

Thermal curing kinetics of trimethylolpropane triacrylate and ethoxylated (3) trimethylolpropane triacrylate with benzoyl peroxide

, 2012
Thermal curing kinetics of two systems, trimethylolpropane triacrylate (TMPTA) with benzoyl peroxide (BPO), and ethoxylated (3) trimethylolpropane triacrylate (ETPTA) with benzoyl peroxide, were investigated at different ratios in weight percentage using

Occupational Contact Allergy to Components of Epoxy Resin Systems: Descriptive and Comparative Epidemiological Analyses Based on IVDK Data 2008–2022

Contact Dermatitis, Volume 95, Issue 5, Page 482-491, November 2026.
This study analyzes patch test data from 23 969 patients with occupational dermatitis to characterise sensitization to bisphenol A diglycidyl ether (DGEBA), reactive diluents, and amine hardeners. The findings show an overall decline in DGEBA sensitization with fluctuations, substantial co‐sensitization, and markedly increased risks in construction ...

Tetrahydrofurfuryl Methacrylate and Isobornyl Acrylate: Possible New Sensitisers in Hearing Aid Ear Moulds

Contact Dermatitis, Volume 95, Issue 5, Page 492-497, November 2026.
A case series of eight patients with allergic otitis externa from contact allergy to hearing aid ear moulds is presented. All were patch test positive to tetrahydrofurfuryl methacrylate and three to isobornyl acrylate. It is postulated that these are likely relevant allergens present in such devices. ABSTRACT Background Allergic contact dermatitis from

Innovative Metal‐Modified Resins via 3D Printing of Triply Periodic Minimal Surface Structures

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
A solvent‐free dual‐monomer strategy enables the direct 3D printing of nickel‐containing TPMS catalyst supports with uniform metal distribution and preserved open‐channel architecture. The resulting structures exhibit excellent printability, thermal and water stability, and enhanced flexibility, offering a promising platform for next‐generation ...
