Resin cross-linking

Page/Page column 4, (2010/02/17)
A method of effecting cross-linking of a resin comprises generating vinyl sulfonyl moieties in situ with the resin, said sulfonyl moieties then undergoing a reaction which effects cross-linking of the resin. The vinyl sulfonyl moieties may be generated as a result of a loss of a liquid carrier for the resin to be cross-linked. The cross-linking reaction may result from reaction of the vinyl sulfonyl moieties with nucleophilic groups in the resin composition. The resin may be a co-polymer of a compound of formula (IV) with other olefinically unsaturated monomers.

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 Cl-5 alkyl group; and Q is bromo, chioro, iodo, triflate or tosylate. These monomers are of utility in the preparation of cross-linkable resin compositions
