Title:
PHOTO-SETTING ADHESIVE COMPOSITION
Document Type and Number:
Japanese Patent JPH02284978
Kind Code:
A
Abstract:

PURPOSE: To obtain the subject composition, consisting essentially of a liquid polymer, prepared by hydrogenating a specific liquid polyisoprene and having specified photopolymerizable groups at both terminals and excellent in heat, water resistance, etc.

CONSTITUTION: The objective composition obtained by hydrogenating ≥50%, (preferably ≥80%) unsaturated bonds in a liquid polyisoprene, prepared by radially polymerizing isoprene monomer, etc., using an azo compound, etc., as a polymerization initiator, etc., and having 700-7000 (preferably 1000-5000) number-average molecular weight to provide a hydrogenated liquid polyisoprene, mixing and reacting the above-mentioned hydrogenated polyisoprene with an organic polyisocyanate compound, providing a prepolymer, reacting the resultant prepolymer with an ester having a photopolymerizable group, such as acryloyl, methacryloyl, acrylamide or methacrylamide, affording a hydrogenated liquid polyisoprene having the photopolymerizable groups at both terminals and further blending the above-mentioned hydrogenated polyisoprene having the photopolymerizable groups as an essential component with benzophene, toluene, etc.
