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.
