摘要: Pulverulent polymers of acrylic acid and methacrylic are prepared by polymerizing (a) from 100 to 70% weight acid, or a mixture thereof (b) 0 30% vinylsulfonic an alkali metal salt in monohydric C 1 -C 8 -alcohol, water pulverulent bed the presence polymerization initiator 0.05 10 mol % thiocarboxylic and/or mercaptoalcohol propionic formic as regulators, each percentage being based on monomers used polymerization, maintaining state during removing heat distilling off solvent recirculating reaction mixture.
