INTERNALLY PLASTICIZED POLYMER LATEX

摘要

INTERNALLY PLASTICIZED POLYMER LATEX This invention relates to a latex of internally ? 75-119A plasticized polymer particles, low in viscosity although high HLG/sjg 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-swellab1e 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.
