Abstract
A method for emulsion polymerization of butadiene comprises adding an acrylic latex to the emulsion polymerization medium in an amount effective to increase the average particle size of the resulting polybutadiene latex. The particles of the resulting polybutadiene latex may also exhibit a desirable spherical shape.
Claims10
A method for emulsion polymerization of butadiene in an emulsion polymerization medium, comprising providing an emulsion polymerization medium containing monomer consisting essentially of butadiene and up to about 50% by weight of an aryl olefin comonomer, and a soap, and adding an acrylic latex to the emulsion polymerization medium during the polymerization reaction in an amount of from about 0.1 to about 10 parts by weight, on a dry basis, per 100 parts by weight of butadiene included in the emulsion polymerization medium.
