Abstract
The present invention relates to a method of making monomers of the formula X═C(H)—Y—S02-CH2-CH(R)—OH which comprises reacting a compound of the formula Q-Y—S02-CH2-CH(R)—OH with a vinyl-containing organometallic reagent comprising a substituted or unsubstituted moiety X═, wherein X═ is a group selected from CH2=, MeO2C(H)C═, MeO2C(Me)C═ and MeC02C═; Y is an optionally substituted aromatic or heteroaromatic diradical; R is a hydrogen or C1-5 alkyl group; and Q is bromo, chloro, iodo, triflate or tosylate. These monomers are of utility in the preparation of cross-linkable resin compositions
