ABSTRACT:
Novel compounds which are the products of monomeric organic reactants containing one or more active hydrogen atoms as determined by the Zerewitinoff method, e.g., a polyol, and organic polyisocyanates, e.g., diisocyanates, in such amounts as to provide about two isocyanate groups for each active hydrogen-containing group thereby forming isocyanate terminated intermediates which are reacted with monomeric organic reactants having at least one active hydrogen-containing group and preferably also an unsaturated group, preferably in a terminal position. One of the monomeric organic active hydrogen-containing reactants must have only one active hydrogen. The novel compounds of this invention which have unsaturated groups are useful as monomers especially in systems utilizing free radical generating addition polymerization initiators which are activatable by actinic light and may be used in the preparation of finishes for woods and metals or in the formulation of inks, both of which may be solvent-free and are curable by exposure to actinic light. Those of the compositions of this invention which do not contain unsaturation may be used as plasticizers in the aforementioned formulations.
