Polymeric Polyaldehyde Approach to Develop Robust Dynamic Covalent Adaptive Polyimine Networks

Macromolecular Rapid Communications, Volume 47, Issue 20, 20 October 2026.
A versatile approach exploring the synthesis of polymeric polyaldehydes with a polyacrylate backbone bearing pendant aldehyde groups to develop dynamic polyacrylate‐polyimine hybrid materials capable of the built‐in ability for extended operation and enhanced reliability. ABSTRACT Polyimine‐based covalent adaptive networks crosslinked with Schiff bases

Bound Rubber and Mechanical Properties of Diene Polymers

, 1958
1. Tensile strength is apparently a function of the particle size of the pigment and how well it is dispersed in a polymer. 2. Modulus and abrasion resistance are apparently functions of the interaction of the pigment and the polymer.

Development and Characterization of Thermo‐Responsive Shape Memory Composite of Polybenzoxazine and Modified Ultrafine Fully Vulcanized Natural Rubber (UFPNR) Filler

SPE Polymers, Volume 7, Issue 4, October 2026.
Tough Thermo‐Responsive Composite from PBA‐a and Monomer Grafted UFPNR. ABSTRACT In this study, various types and concentrations of ultrafine fully vulcanized powdered natural rubbers (UFPNR) were evaluated on how they affect the toughness of bisphenol A polybenzoxazine (PBA‐a).

Phase Behavior of Brominated Poly(Isobutylene-co-4-Methylstyrene)/General Purpose Rubber Blends

, 1999
The thermodynamic interaction and phase behavior of elastomeric blends, specifically brominated poly(isobutylene-co-4-methylstyrene) and a general purpose rubber, polybutadiene, have been examined using small-angle neutron scattering (SANS) and cloud ...

The Filler Network Index: A Viscosity‐Independent Rheological Criterion for Quantifying Silica Architecture in Unvulcanized Rubber Compounds

SPE Polymers, Volume 7, Issue 4, October 2026.
SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

Can Emulsion Styrene Butadiene Rubber Reinvent Itself Through Molecular Architecture, Interface Engineering, and Sustainable Feedstocks?

SPE Polymers, Volume 7, Issue 4, October 2026.
Emerging Directions in Emulsion Styrene‐Butadiene Rubber: Molecular Design, Filler Interfaces, and Sustainable Feedstocks. ABSTRACT Emulsion styrene butadiene rubber (eSBR) is often viewed as a mature elastomer platform whose role in high‐performance tire applications is increasingly challenged by solution SBR (sSBR), particularly in silica‐filled ...

Facile Approach to Modulating Stereochemistry in Ring‐Opening Metathesis Polymerization of Cyclooctadiene

Journal of Polymer Science, Volume 64, Issue 19, Page 4037-4046, 1 October 2026.
The stereochemistry of polybutadiene made by ring‐opening metathesis polymerization (ROMP) evolves both during and after polymerization, as secondary metathesis shifts cis‐rich kinetic products toward trans‐rich equilibrium compositions. By tuning catalyst identity, additives, temperature, and reaction time, polybutadienes with 28%–80% trans content ...

Screening Surface Modifications to Benzene to Improve Solubility in Hydroxyl‐Terminated Polybutadiene (HTPB)—A DFT Demonstration

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 10, Page 1657-1662, October 2026.
ABSTRACT The objective of this paper is to demonstrate the advantage of computationally pre‐screening surface‐modifying material candidates, using density functional theory (DFT), to inform experimental synthesis and formulation efforts. This demonstration focuses on improving the solubility of benzene‐based materials in hydroxyl‐terminated ...
