Abstract
A plurality of substituted styrene monomers, for example, urea substituted, is disclosed as well as polymers and copolymers made therefrom. Various thermoset plastic components can be reacted with the monomers, polymers, or copolymers of these substituted styrenes, as for example epoxy, which form a crosslinked system useful as an adhesive or a fiber reinforced substrate for circuit boards. The monomers are made by reacting aminostyrene type monomers with isocyanate containing molecules. One specific monomer is made by reacting a substituted aminostyrene with a monoisocyanate and has the following formula ##STR1##
