Processes of spray drying polymer-containing dispersions, water- in- oil emulsions and water-in-oil microemulsions

摘要

Processes for spray drying water-soluble and water-swellable vinyl- addition polymer-containing dispersions, emulsions and microemulsions to obtain substantially dry water-soluble or water- swellable polymer particles, compositions of substantially dry water- soluble or water- swellable polymer particles, methods of agglomerating spray-dried polymer particles, and methods of using spray-dried polymer particles and agglomerates in water-treating, mining, paper, food processing, soil conditioning, solution thickening, biotechnological, and oil recovery applications are disclosed.
