ABSTRACT:
This invention relates to a latex of internally plasticized polymer particles, low in viscosity although high in hydrophilic components and film forming at temperatures below the calculated Tg of the polymer. The polymer may be prepared by a multistage emulsion polymerization process. The first stage is highly water-swellable or water-soluble. The principal second or later stage is less hydrophilic and of higher Tg than the first stage and is polymerized in the emulsion in the presence of the first stage.
