Abstract
PURPOSE: A polymer latex, having improved mechanical stability at a high temperature, capable of forming a film having improved tensile strength and adhesive property, and obtained by introducing dicarboxylic acid groups into a vinyl aromatic compound -conjugated diene compound block copolymer.
CONSTITUTION: An unsaturated dicarboxylic acid or a derivative thereof is grafted onto a vinyl aromatic compound -conjugated diene compound block copolymer, preferably styrene -butadiene block copolymer, to give a modified block copolymer containing 1W50 dicarboxylic acid groups or derivative groups thereof introduced into one molecule. A solution of the modified block copolymer in an organic solvent is emulsified in water or its mixture with an emulsifier, e.g. anionic, nonionic or anionic -nonionic surfactant, and the organic solvent is removed from the resultant emulsion. Preferably, an aqueous solution of an alkali metallic hydroxide is used as the water in the emulsification to convert the dicarboxylic acid groups into the carboxylate.
