    摘要: Fine particulate thermoplastic polymers [e.g., hydrophobically modified polyether-polyurethanes, polyacrylates, polyvinyl alcohol, polyether-polyols, polyacrylamide, aminoplast-polyethers and poly(acetal- or ketal-polyethers] having reduced bulk density, process of making same by dissolving the polymer and rapidly insolubilizing the polymer from the solution and process of using aqueous suspensions of such polymers as thickeners for aqueous systems.
