Synergistic Effects of Phenolic Resin and Polymer Architecture on Crosslink Density and Damping in Poly(Epichlorohydrin‐Co‐Ethylene Oxide‐Co‐Allyl Glycidyl Ether) (GECO) Elastomers

Journal of Polymer Science, EarlyView.
Phenolic resin reduces crosslink density and alters the viscoelastic response of GECO elastomers. The magnitude of these changes depends strongly on polymer architecture. Damping performance is governed by the combined effects of network density and molecular structure, not resin content alone, providing a framework for designing advanced vibration ...
