Title:
(METH)ACRYLOYL-TERMINATED POLYISOBUTYLENE POLYMER, METHOD FOR PRODUCING SAME, AND ACTIVE ENERGY RAY-CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2013/047314
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a polymer which has a smaller halogen atom content remaining in the polymer; a simple method for producing the polymer; an active energy ray-curable composition which can be quickly cured by irradiation of a small amount of light; and a cured product of the active energy ray-curable composition. The purpose of the present invention is able to be achieved by an active energy ray-curable composition which is characterized by containing a polyisobutylene polymer (A) represented by general formula (1) and an active energy ray polymerization initiator (B). (In the formula, R1 represents a monovalent or polyvalent aromatic hydrocarbon group or a monovalent or polyvalent aliphatic hydrocarbon group; A represents a polyisobutylene polymer; R2 represents a divalent saturated hydrocarbon group having 2-6 carbon atoms, said group containing no heteroatom; each of R3 and R4 represents a hydrogen atom, a monovalent hydrocarbon group having 1-20 carbon atoms or an alkoxy group; R5 represents a hydrogen atom or a methyl group; and n represents a natural number.)
