  • Styrene type monomers containing substituents thereon, e.g. urea, and polymers and copolymers thereof
    Patent number: 5444129
    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.

  • Polymers containing pendant urea groups
    Patent number: 4985522
    Abstract: There is disclosed a family of new vinyl monomers capable of forming polymers by free radical polymerization. The vinyl monomer is of the formula ##STR1## wherein R.sub.1 and R.sub.2 are substituted or unsubstituted hydrocarbons, X is O, NH or NR.sub.3, and R.sub.3 is substituted or unsubstituted hydrocarbon.The intermediates in the synthesis of these monomers are new beta-chloroanaline ureas. The polymers are useful in film and fiber formation and display good toughness. These new vinyl monomers also form a cyclic monomer.
    Type: Grant
