Soap-free carboxylated polystyrene latexes have been prepared by copolymerizing acrylic acid (AA) in a wide range of the degree of neutralization using a slight amount of soap; and the distribution of carboxyl groups was investigated from the determination of carboxyl groups localized on the surface

Alkali-soluble random copolymer (ASR), poly(styrene/a-methylstyrene/ acrylic acid) [M n : 4,300; acid number: 190], was used as a polymeric emulsifier in the emulsion polymerization of styrene and methyl methacrylate, respectively. ASR containing a large number of carboxyl groups could form aggregat
Acrylic acid was polymerized in aqueous medium using the peroxy salts Na,S,O,, (NH,),S,O,, and KIO, as initiators. Of those salts, Na,S,O, proved to he the most advantageous. Detailed investigations of the polymerization process were carried out with Na,S,O, alone and with different reductants, name
