摘要：

Novel unsaturated polyesters designated NUP-I, NUP-II, and NUP-III have been synthesized by 1-step, 2-step, and 3-step polyesterification processes, respectively, and their possible structures have been assigned with the help of IR and NMR. Trends in the properties of uncured novel unsaturated polyesters (gel time and exotherm peak temperature) as well as cured novel unsaturated polyesters [tensile strength, elongation, bond strength with composite modified double-base (CMBD) propellants, Shore hardness, nitroglycerine (NG) absorption, thermal conductivity, and heat resistance] support these assigned structures.
