Morgan, C R

A curable composition comprising compatible polyene and polythiol in which both the components ae derived from a hydantoin glycol is claimed. The polyene is typically a reaction product of N,N'-bis(2-hydroxyethyl) dimethylhydantoin, 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, chemically resistant, cross-linked polythioether products.
