摘要： Brominated butadiene polymers are recovered from solution and formed into particles by spraying the solution onto a heated, mechanically agitated bed of seed particles. The droplets contact the seed particles in the bed and form a polymer layer on the outside of the seed particles, thereby enlarging them. The solvent is removed from the droplets after they make contact with seed particles in the bed. The process allows for the simultaneous removal of solvent and formation of somewhat large particles. The process forms at most small amounts of agglomerates and fines.

摘要： Methods are provided for making a solution masterbatch containing a diene elastomer in an organic solvent and a reinforcing silica filler dispersed therein, comprising the steps of (a) mixing a precipitated silica having an average particle size substantially equivalent to an average particle size of a powdered silica, with a diene elastomer in a first organic solvent; and (b) desolventizing the mixture to form a solution masterbatch preparation. The use of such desolventized solution masterbatches in vulcanizable rubber compounds results in excellent processing characteristics with improved dispersion of fillers, including polymeric nanoparticles. The compounds also demonstrate improved properties, including reduced hysteresis.

摘要： The apparatus proposed herein relates to mass-exchange apparatus for isolating polymers from hydrocarbon solutions. The apparatus comprises a vertical column provided with a device for producing polymer crumb and an aqueous suspension, a device for feeding live steam, and contact trays which divide the column into compartments as for height. The device for producing polymer crumb and aqueous suspension is accommodated in the top portion of the vertical column and is essentially a chamber established on at least one side by the overflow baffle. The chamber accommodates the water supply nozzle and a conventional injector-type polymer crumb former. Such an arrangement of the device for polymer crumb formation and producing aqueous suspension results in a simplified construction of the entire apparatus and diminished overall dimensions thereof, as well as to a simpler attendance of the apparatus.

摘要： Discrete, finely divided, tack-free, pourable elastomer particles are prepared from a filler-containing organic solventelastomer suspension containing the elastomer dissolved in a volatile inert organic solvent and a solid, finely divided elastomer filler, by flash evaporation of the organic solvent to form discrete finely divided, tack-free elastomer particles. The process can be applied to solid elastomers or to postpolymerization elastomer solutions, and is particularly suitable for preparing pourable, carbon black containing elastomer particles to be formed into shaped objects such as tires.
