| 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. | ||||||
