Abstract

ABSTRACTEpichlorohydrin (ECH)‐based elastomers represent a significant class of materials, offering dynamic properties similar to natural rubber but with enhanced heat and chemical resistance. They also offer improved low‐temperature flexibility due to the presence of pendant chloromethyl groups on the main chains with etheric oxygens. This study investigates the effect of molecular architectures on the damping properties of elastomers derived from ECH terpolymers, specifically poly(epichlorohydrin‐co‐ethylene oxide‐co‐allyl glycidyl ether) (GECO) at various temperatures. Cylindrical samples were subjected to cyclic compression tests at three different temperatures. The results demonstrate that the molecular architecture of GECO polymers significantly influences the damping properties of the resulting elastomers, with varying effects observed at different temperatures.
