Abstract
A novel functional high polymeric substance having .alpha.,.beta.-unsaturated carboxylate group, which is obtained by reacting a liquid high polymeric substance containing carbon-to-carbon unsaturated double bond or a solution of said high polymeric substance with .alpha.,.beta.-unsaturated carboxylic acid and its derivative in the presence of pseudo halogen compound. A rubber composition suitable for sealant is obtained by compounding said functional high polymeric substance with a plasticizer and/or a filler.
Claims18
A high polymer substance having .alpha.,.beta.-unsaturated carboxylate group and anaerobic curability and curability under ultraviolet irradiation obtained by reacting (A) a liquid high polymeric substance containing carbon-to-carbon unsaturated double bond or a solution of a high polymeric substance containing carbon-to-carbon unsaturated bond with (B) an .alpha.,.beta.-unsaturated carboxylic acid or its derivatives selected from the group consisting of acrylic acid, methacrylic acid, 2-hydroxyethyl acrylate and 2-hydroxyethyl methacrylate in the presence of (C) at least one pseudo-halogen compound selected from the group consisting of alkylhypohalite, halogenated isocyanate, N, N-dihaloalkyl urethane, N,N-dichloroaryl sulfonamide and N-halocarboxylic acid imide, wherein the mole ratio of (A) to (B) is in the range of from 1:0.5 to 1:2.5.
