Performance and Kinetics Study of Self-Repairing Hydroxyl-Terminated Polybutadiene Binders Based on the Diels–Alder Reaction [PDF]
Polymers, 2017 Based on the Diels–Alder reaction and hydroxyl-terminated polybutadiene (HTPB) binders of solid propellants, two novel compounds—furfuryl-terminated polybutadiene (FTPB) and trifurfuryl propane (TFP)—were designed and synthesized, and their structures were characterized.

ACS OmegaFundamental knowledge on how polymer architecture affects curing and material properties of solid rocket motors (SRMs) using hydroxyl-terminated poly-(butadiene) (HTPB) as a prepolymer has historically been based on studies employing impure samples. Herein, we present the synthesis of highly controlled HTPB via reversible addition-fragmentation chain ...
