the shape memory polymers disclosed are a reaction product of at least one reagent containing two active amino - hydrogen or two active phenolic - hydrogen with at least one multifunctional cross linking reagent which contains at least three or more active amino - or phenolic - hydrogen or is a reagent containing at least three glycidyl ether moieties which is then further mixed with at least one diglycidyl ether reagent whereupon the resulting mixture is cured and has a glass transition temperature higher than 00 c . this reaction creates crosslinking between the monomers and polymers such that during polymerization they form a crosslinked thermoset network .
