Abstract
This invention relates to an improved continuous emulsion polymerization process for preparation of flame-retardant latex. Specifically, this invention relates to a novel method for the preparation of high solids, flame-retardant latex with high chlorine content in high conversion containing polymerized vinylidene chloride and at least one monoethylenically unsaturated carboxylic acid. The improved continuous polymerization process is characterized by continuous addition of all of the vinylidene chloride and all of the monoethylenically unsaturated carboxylic acid monomers along with a portion of the remaining monomers to a first reaction vessel followed by the subsequent continuous addition of the rest of the remaining monomers and additional surfactant solution to a second reaction vessel in a chain consisting of three or more reaction vessels. The flame-retardant latices produced by the process of the invention have improved physical and application properties.
