dispersant water and polymer and introduce this mixture continuously to the reactor while continuously removing from another part of the reactor the product dispersion the amount of water used in relation to the polymer dispersed generally ranges from about 0 7 to about 10 parts by weight of water per part of normally solid polymer higher ratios are operable but uneconomical whereas lower ratios although usable present operational difficulties the preferred range is between about 1 and about 6 parts per part of polymer the amount of dispersant should be sufficient to provide a dispersion of the resin in the water under the selected conditions very good dispersions can be obtained at amounts within the range of from about 6 to about 100 weight parts dispersant per 100 weight parts of resin and as such these amounts are preferred there is no upper limit on the amount of dispersant which can be employed except that exceeding the amount beyond that required to provide an acceptable dispersion may be economically wasteful the amount of alkanolamide surface active agent to be employed for a given resin and desired average particle size can be empirically determined through simple and routine experimentation the weight ratio of polymer to.
