ABSTRACT:
This invention is directed to polyenes derived from hydantoin acids, amines and esters. The polyene is typically a reaction product of a hydantoin amine, e.g., N,N'-bis(3-aminopropyl)-dimethylhydantoin, a diisocyanate and an unsaturated ether, e.g., trimethylolpropane diallyl ether. Upon exposure to a free radical generator, e.g., actinic radiation, in combination with a polythiol, this polyene cures to a solid, insoluble, chemically resistant, crosslinked polythioether product having excellent heat stability.
