摘要:Provided is a convenient method for the synthesis of quaternary ammonium sulfonate compounds which are useful as curing catalysts for one-part thermosetting resin compositions which maintain storage stability at room temperature. The compounds are synthesized by subjecting in one step a benzyl alcohol optionally having on the benzene ring and/or the α-position one or more substituent groups to reaction with a corresponding tertiary amine and an organic sulfonic acid chloride.

标题:Initiator compositions and methods for their synthesis and use
发明人：CRIVELLO JAMES V
摘要:Cationic polymerization initiators of formula ##STR1## are disclosed. The acyl sulfonium salts of the present invention differ from known acyl sulfonium initiators in that the substituents R 2 and R 3 on the sulfur are larger and more complex than the lower alkyl and lower alkylene of known photoinitiators. Processes for the synthesis of the novel acyl sulfonium salts and prepolymer compositions containing them are also disclosed.
