the particles did not cake together and could always be broken up and redispersed when dry the product comprised fine agglomerates which stuck together slightly but could always be broken up using the procedure of example 1 a dispersion was made from 150 g of the copolymer of example 1 412 ml of distilled water and as dispersant 53 6 g of triton x 200 rohm and haas company the sodium salt of alkylaryl polyether sulfonate with 2 g of sodium hydroxide the temperature at the start of the 7 minute dispersing period 3700 rpm was 202 u00b0 c dry ice was applied to the reactor in the second minute of the 7 minute period at the end of which period the temperature had fallen to 176 u00b0 c after cooling to 100 u00b0 c the reactor was opened 100 of the copolymer was dispersed to a very fine dispersion a portion of the dispersion approximately 60 g was filtered and washed with water it showed the same behavior as dispersions of this copolymer made with pluronic dispersants the filter cake coalesced thereafter 90 g polymer was cleaned up by first filtering redispersing the filter cake in a waring blender in 300 ml of water containing 1 5 of diethanolamine refiltering and repeating this washing two more times the final filter cake contained 52 4 of water a portion of the final filter cake was dried at room temperature after breaking up in a waring blender the dried product was made up of small aggregates of particles exhibiting slight coalescence but which could be broken apart three portions of tacky nominally 3 8 inch pellets of an ethylene vinyl acetate copolymer containing about 40 weight percent of.
