ABSTRACT:
An emulsion polymerization method for a brominated styrene is provided in which upon emulsion polymerizing a brominated styrene, an organic solvent which dissolves the brominated styrene and is sparingly soluble in water is added in an amount of 1 to 500 parts by weight per 100 parts by weight of the brominated styrene. According to this method, brominated polystyrenes can be produced which have acceptable hues and excellent physical properties and smell no offensive odor during the step of molding.
