To provide a new ethylenically unsaturated group-containing isocyanate compound, to provide a method for producing the same, to provide a reactive monomer obtained from the isocyanate compound, and to provide a reactive polymer and applications thereof, respectively.
The new ethylenically unsaturated group-containing isocyanate compound is represented by the formula(I)( wherein, R1 is a 1-10C straight-chain or branched saturated aliphatic group; R2 is H or methyl; R3 is a 0-5C straight-chain or branched alkylene group; and R4 is H, a 1-6C straight-chain or branched alkyl or aryl ). The reactive monomer is obtained by reaction of the above isocyanate compound with an active hydrogen-bearing functional group-bound compound. The reactive (meth)acrylate polymer is obtained by reaction of the above isocyanate compound with a polyhydroxy compound composed of recurring units each to which an active hydrogen-bearing functional group is bound.
