CATIONICALLY POLYMERIZABLE RESIN COMPOSITION

摘要

The addition of a compound latently or directly generating a carbocation to a polymerization system containing a compound capable of undergoing cationic ring-opening polymerization was found to enable the reaction of the system to efficiently shift from an initiation reaction to a growth reaction and to impart activity in polymerization. A cationically polymerizable resin composition is provided which is characterized by comprising (A) a compound having, in the molecular chain, at least one functional group undergoing cationic ring-opening polymerization, (B) a cationic polymerization initiator, and (C) a compound which, upon irradiation with a magnetic wave or particulate beam, generates an active species which acts on the cationic polymerization initiator (B) to cause it to generate a carbocation. With respect to the initiation reaction of a compound capable of undergoing cationic ring-opening polymerization, it was found that when a compound latently or directly generating a carbocation is added to a polymerization system containing the compound, the reaction of the system efficiently shifts from an initiation reaction to a growth reaction and activity in polymerization is imparted.
