Abstract
Aqueous dispersions of water soluble nonionic and anionically charged vinyl and allyl addition polymers can be obtained by polymerizing in the presence of an anionically charged water soluble polymer stabilizer in a saturated salt solution. Methods for the preparation of these polymers, and their compositions are disclosed.
