Method for producing carboxylated nitrile rubber
14 Dec 21
A method for producing a carboxyl group-containing nitrile rubber including the steps of: polymerizing a monomer mixture including an α,β-ethylenically unsaturated nitrile monomer and a carboxyl group-containing monomer in a solvent; terminating a polymerization reaction by adding a nitrous acid salt and a water-insoluble hydroquinone as polymerization terminators to the polymerization system, thereby obtaining a dispersion of the carboxyl group-containing nitrile rubber having a pH of 7 or below; and coagulating the dispersion of the carboxyl group-containing nitrile rubber, thereby obtaining the carboxyl group-containing nitrile rubber in the solid state, wherein the amount of the nitrous acid salt to be used is 0.15 parts by weight or less relative to 100 parts by weight of the monomer mixture used in the polymerization reaction.
