parts deionized water 0 25 part 1 t butyl hydroperoxide and n n methylene bisacrylamide mba are added this aqueous phase is mixed with an oil phase containing 77 8 parts of low odor paraffin oil 3 6 parts sorbitan sesquioleate and 21 4 parts polyoxyethylene sorbitol hexaoleate this emulsion is deaerated with nitrogen for 20 minutes the polymerization is then initiated with gaseous so 2 the polymerization is then allowed to exotherm to 40 u00b0 c and is controlled at 40 u00b0 c 5 u00b0 c with ice water the ice water is removed when cooling is no longer required the nitrogen is continued for one hours the total polymerization time is 2 5 hours if desired the polymer may be recovered from the emulsion by stripping or by adding the emulsion to a solvent which precipitates the polymer e g isopropanol filtering off the resultant solids drying and redispersing in water at the time of use e g as a paper making additive the recovered polymer may be dispersed in water the emulsion microbeads may also be directly dispersed in water depending on the surfactant and levels used in the emulsion dispersion may require using high a hydrophilic lipophilic balance hlb inverting surfactant such as an ethoxylated alcohol polyoxyethyllated sorbitol hexaoleate diethanolamine oleate ethoxylated laurel sulfate etc as in known in the art the procedure for preparing amphoteric emulsions e g 15aa 60amd 25 dimethylaminoethylacrylate dmea 349 ppm mba is repeated for the preparation of the anionic emulsions with the exception that the concentration of the individual monomers employed are adjusted accordingly various monomers are polymerized in accordance.
