Abstract
Reactive multifunctional imide monomers have been discovered from which radiation curable oligomers and polymers may be derived. The reactive imide monomers have at least one functional group which is polymerizable under free radical or ionic polymerization conditions with other similar functional groups. However, the same functional group and reaction product derived therefrom is substantially not subject to cleavage by oxidation or hydrolysis. The reactive imide monomer also contains at least one other functional group which remains intact under the above-described polymerization conditions to form a part of a side chain of the resultant polymer and will cross-link or cure by 2+2 cyclo-addition with other like functional groups upon irradiation.
