摘要： A process to produce a dispersion comprising feeding ethylcellulose polymer and a dispersant into a melt and mix zone of an extruder wherein the ethylcellulose polymer and dispersant are melted and mixed together to form a melt; conveying the melt to an emulsification zone of the extruder in which the temperature and pressure are controlled; feeding a base and water into the emulsification zone wherein the melt is dispersed to form a high internal phase emulsion; conveying the emulsion to a dilution and cooling zone of the extruder; and feeding water into the dilution and cooling zone to dilute the high internal phase emulsion thereby forming an aqueous dispersion is provided.

摘要： The present invention relates to an aqueous dispersion of a class of organic phosphate functionalized microspheres having a particle size in the range of from 1 µm to 25 µm, and a process for preparing the dispersion. The microspheres, which have a low coefficient of variation and low gel concentration, are useful in coatings applications, especially where a matte finish is desired.

摘要： The present invention relates to a process for preparing an aqueous dispersion of a vinyl acetate polymer comprising the step of polymerizing vinyl acetate under emulsion polymerization conditions in the presence of a chain transfer agent which is a hypophosphite salt or X-R 1 -SH, where R 1 is a C 1 -C 4 alkyl group and X is sulfonate, hydroxyl, sulfate, phosphate, phosphonate, carboxylic acid or a salt thereof, or C 1 -C 3 -alkyl carboxylate. The process provides a way of lowering the viscosity of the vinyl acetate polymer at a given solids content.
