    • PURPOSE: Provided is a method for producing coagulated particles of rubber latex excellent in stability, which shows small changes of particle diameter with the lapse of time. CONSTITUTION: The method comprises the steps of (i) forming a seed synthetic rubber latex by typical emulsion polymerization, (ii) mixing an ion-exchanged water, pH adjusting agent, and emulsifier into a unsaturated acid-containing copolymer latex having solid content of 10-50 wt%, to pre-treat the latex so as to have solid content of 1-10 wt% and pH of 3-11, (iii) introducing the pre-treated latex into the seed synthetic rubber latex formed from the step(i), and (iv) adding an ion-exchanged water, anionic emulsifier, nonionic emulsifier, antifoaming agent, and water-soluble polymer to the seed synthetic rubber latex. The method is characterized in that the water-soluble polymer is selected from the group consisting of polyethylene glycol having number average molecular weight of 200-20,000, copolymer of ethylene glycol and ethylene oxide, and a copolymer of polypropylene glycol and propylene glycol and ethylene oxide.
