ABSTRACT:
Carboxyl or carboxyl salt containing polymers are prepared by polymerizing carboxyl containing monomers wherein greater than one percent of the carboxyl groups are neutralized with an alkali, ammonia or an amine, optionally copolymerized with other vinylidene monomers containing at least one terminal CH.sub.2 .dbd.CH< group dissolved in a solvent for the monomers which is a non-solvent for the polymer with a free radical catalyst, so that the resulting polymer is obtained suspended as a fine, readily recoverable substantially non-swollen fine powder. The solvents used are moderately to strongly hydrogen bonded and have solubility parameters of from about 8 to 15.
