Abstract
An improved vesicular matrix prepared by the emulsion polymerization of methacrylonitrile, either alone or with a small amount of comonomer, in the presence of a cationic emulsifier. The resulting polymer or copolymer can be used alone, or the polymer or copolymer may be blended with a small amount of a highly incompatible polymer or copolymer, to provide an improved vesicular matrix.
