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.
一种实现
树脂交联的方法包括在
树脂中原位生成
乙烯磺酰基团,然后这些磺酰基团经历一种反应,从而实现
树脂的交联。
乙烯磺酰基团可能是由于
树脂交联所需的液体载体的流失而生成的。交联反应可能是由
乙烯磺酰基团与
树脂组成中的亲核基团发生反应而导致的。
树脂可以是化合物(IV)的共聚物与其他烯烃不饱和单体的共聚物。
