INFLUENCE OF FLUOROCARBON AND HYDROCARBON EMULSIFIERS ON THE RATES OF EMULSION POLYMERIZATION OF STYRENE AND α, β, β-TRIFLUOROSTYRENE

Received Date: 7 May 1964

Rates of emulsion polymerization of styrene and α，β，β-trifluorostvrene were measured dilatometrically in the presence of different emulsifiers．The following emulsifiers were used： fluorocarbon carboxylates，H(CF2)nCOOK，n=6，8，10 and F2CI(CFCICF2)3 COOK，and hydrocarbon carboxylates H(CH2)nCOOK，n=7， 11．Polymerization rates of α，β，β-trifluorostyrene are lower than that of styrene．With hydrocarbon carboxy-lates as emulsifiers，polymerization rates of styrene and α，β,β-trifluorostyrene are both greater than that with fluorocarbon carboxylates．In the ω-hydroperfluorocarboxylate series，H-(CF2)nCOOK n=6，8，10，the n=8 salt gave the best result．
