ABSTRACT:
A curable composition comprising compatible polyene and polythiol in which both the components are derived from a hydantoin glycol. The polyene is typically a reaction product of N,N'-bis(2-hydroxyethyl) dimenthylhydantoin, a diisocyanate and an unsaturated alcohol, e.g., allyl alcohol. The polythiol is typically a reaction product of N,N'-bis(2-hydroxyethyl) dimethylhydantoin and a mercapto carboxylic acid, e.g., .beta.-mercaptopropionic acid. Upon exposure to a free radical generator, e.g., actinic radiation, this polyene-polythiol composition cures to solid, insoluble, chemical resistant, crosslinked polythioether products.
