ABSTRACT:
The method of preparing synthetic powders containing emulsifiers having good paste qualities by spray-drying polymer dispersions through a two-fluid atomizer having a spray ratio of about 1.6 to 5.0 kg. of spray air for each kg. of dispersion is improved. The polymer dipersions are prepared by emulsifying vinyl chloride monomer or a mixture of vinyl chloride monomer and unsaturated polymerizable compounds and polymerizing the monomers to produce polymers and copolymers of vinyl chloride. The improvement in paste qualities of the powders is achieved by introducing the spray dried powder into an air jet having a velocity from about 330 to 550 meters per second and having a weight ratio of gas to solids ranging from 1:10 to 5:1.
