发明名称 METHOD FOR PRODUCING THERMOSENSITIVELY COAGULABLE LATEX
摘要 PROBLEM TO BE SOLVED: To provide a method for producing a highly thermosensitively coagulable latex having good storage stability even if added with a thermosensitive coagulant. SOLUTION: This method for producing a thermosensitively coagulable latex comprises the following process: 100 pts.wt. of an ethylenically unsaturated monomer mixture including a diene-based unsaturated monomer is put to seed emulsion polymerization using, as the anionic emulsifier A, diphenyl ether sulfonate A1, diphenyl ether disulfonate A2 or a fatty acid metal salt A3, in the presence of >=2.5 pts.wt., on a solid basis, of a seed latex B to obtain a latex I, which is then cooled and then added with a thermosensitive coagulant II, wherein the solid weight ratio B/A is 7-13, 1.2-2.0, or 1.5-5, when A1, A2 or A3 is used, respectively.
