Abstract
Gel formation is prevented in the reaction between a sulfonyl-chloride-containing resin and a polyamine by first forming an adduct between the resin with an aminophenol. The prevention of gel formation enables sulfonyl-chloride containing resin to be used in admixture with acrylates and epoxy resin to form a polyamine-curable adhesive composition having excellent adhesive properties and chemical resistance.
