Abstract
Abstract Crosslinkable monomers containing oxazolidinone structures are prepared by reacting polyisocyanates with acrylic esters containing an epoxy group. These polyfunctional monomers can be homopolymerized or copolymerized with other monomers or polymers containing olefinic unsaturation to insoluble, infusible polymers, including copolymers. The monomers and polymers find utility as castings, moldings, impregnants, coatings and for the production of reinforced laminates. Curing can be accomplished by any of the known methods, such as thermally, by the use of catalysts, by ultraviolet light, and by ionizing radiation. The monomers have the formula O-CH-(CHR)xOOCC(Y)=CH2 ¦¦ O=C¦ ¦¦ Q---N-CHR n WHEREIN N HAS A NUMERICAL VALUE OF AT LEAST TWO, X IS 1-8, R is hydrocarbon, Y is H, CH3 or CH, and Q is a polyvalent organic moiety.
