A curing agent for epoxy resins is prepared by (1) reacting a phenol and an aldehyde in the presence of a basic catalyst to form a first reaction product, (2) reacting the first reaction product with a polyamine or a polyamine-epoxy adduct to form a second reaction product containing unreacted primary amine groups, and (3) reacting the second reaction product with a proton donor compound having a pK value of 11 or less to form the curing agent.

A radiation-curable composition is comprised of the reaction product of an amine-terminated (poly)aminoamide and a mono-(meth)acrylate or a poly-(meth)acrylate. The radiation-curable composition is a liquid at room temperature and does not undergo substantial volume contraction upon curing and exhibit excellent adhesion to porous and non porous substrates alike.

The invention provides compounds containing the ring-opening products of ethylenically unsaturated cyclic carbonates for use in preparing hydrogel polymers, as well as methods for their preparation. A preferred method of the invention includes the reaction of nucleophilic compounds containing Si, F, N or O atoms, or combinations thereof, or latent moieties in the form of unsaturated or hydroxylated functional groups, with ethylenically unsaturated glycerol carbonate derivatives. The compounds and hydrogel polymers are useful for the preparation of contact lenses.
