METHOD OF ISOLATING SYNTHETIC RUBBERS FROM LATEXES Russian patent published in 1999 - IPC

Abstract RU 2140928 C1

FIELD: chemistry of polymers, more particularly preparation of synthetic rubbers of emulsion polymerization. SUBSTANCE: method comprises adding organic amine coagulant, subsequently adding calcium or magnesium chloride, or bischofite at amine coagulant to calcium or magnesium chloride or bischofite weight ratio from 10:1 to 1:10 at total amount of mixture of coagulants of 0.01 to 2.00 wt % per rubber. Method makes it possible to improve processibility of process for isolating rubbers from latexes, avoid clogging up of equipment and obtain rubber crumb uniform in size and reduce ash content in rubber. EFFECT: more efficient isolation method. 1 tbl
