<p>A method for producing a carboxyl group containing rubber wherein a dry rubber is produced by carrying out continuous coagulation, dewatering, washing, and drying of a polyvinyl alcohol-containing latex of a rubber containing a carboxyl group in a dewatering/drying apparatus of a screw extruder type, characterized in that use is made of a coagulating agent containing ammonium borate. The method can be used for producing a carboxyl group containing rubber having good vulcanizing characteristics and exhibiting good resistance to scorching in good yield and in a continuous manner.</p> |
