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.
