POLYIONIC POLYMER COMPOUND, IS PRODUCTION AND USE AS A PHOTOINITIATOR

摘要

PROBLEM TO BE SOLVED: To provide a polyionic polymer compound used for modifying a polymer when used as a photoresist or being useful as a photoinitiator for cationic polymerization or crosslinking a monomer. SOLUTION: The polymeric or oligomeric ionic compound consists of a polycationic moiety (A<+> )p containing a plurality of onium units and anions X<-> to the number sufficient to electrically neutralize the compound. The onium unit is a biaryl iodonium, an arylsulfonium, an arylacylsulfonium, a diazonium or the like; and X<-> is an imide anion [RFSO2 NSO2 R'F]<-> or methylide anion [RFSO2 C(Q)SO2 R'F]<-> (wherein Q is H-, Cl-, F-, Br-, CN-, a 1-30C alkyl, a group R"F or a group R"FSO2 ; and RF, RF' and RF" are each fluorine, a perhaloalkyl or the like or may be combined with -SO2 - to form a ring).
