POLYMER CONTAINING ALICYCLE GROUP HAVING ENDOCYCLIC OLEFIN ON SIDE CHAIN AND ACTIVE ENERGY RAY-CURING TYPE COMPOSITION CONTAINING THE POLYMER

摘要

PROBLEM TO BE SOLVED: To obtain a (co)polymer containing a double bond on the side chain, which is mixed with an active energy ray-curable type composition and is applicable to various fields and to provide a simple and practical method for producing the polymer.;SOLUTION: The polymer (C) containing an alicyclic group having an endocyclic olefin on the side chain is obtained from a compound (A) containing an alicyclic group (A1) having an endocyclic olefin and a radically polymerizable group (A2) and a radical polymerization initiator (D) and optionally a compound (B) containing at least one radically polymerizable group in the molecule and having 500-40,000 mass-average molecular weigh. The active energy ray-curable type composition comprises the polymer (C), a polyhydric thiol compound (E) and a photopolymerization initiator (G).;COPYRIGHT: (C)2004,JPO
