ABSTRACT:
Microporous styrene polymers are provided having randomly interconnected open network of irregularly shaped pores whose walls consist of cohered spherical particles of the polymer. These microporous styrene polymers are produced by mixing styrene polymer latex with a water-soluble ether, casting, molding, or impregnating the resulting mixture into a fibrous material, heating same to a temperature of from about 80.degree. C to about 120.degree. C and removing the ether.
