Abstract
Cyanate ester shape memory polymers (SMP). The polymers are preferably formed via reaction of a multifunctional cyanate ester and a mono functional cyanate ester and exist, in one inventive aspect, in the form of a cross-linked thermoset network. Optional catalysts and structural modifiers may be added to the reaction moieties to help control the glass transition temperature of the resulting SMP to greater than 0° C., preferably from about 150° C.-300° C.
