Abstract:
A nonaqueous fluidized polymer suspension containing at least one water-soluble polymer, low molecular weight polyethylene glycol, an optional dissolution additive, and at least one organoclay suspending aid to permit effective long-term, uniform, storage-stable fluidizing of the polymer is provided. Such a novel suspension permits the delivery of the water-soluble polymer as an additive or within a coating for certain substrates in liquid form, when such a component is normally present as a solid, in order to impart excellent fluidity characteristics to the polymer formulation. Such a fluidized polymer suspension exhibits ease-of-use through low suspension viscosity, provides easier handling of such a polymer (in liquid rather than in solid form), provides low environmental toxicity and low volatile organic content, and also permits beneficial treatment of certain substrates with the water-soluble polymer as well as simultaneous treatment thereof with both the polymer and the low molecular weight polyethylene glycol. The inventive fluidized polymer suspension provides excellent delivery capabilities of desirable additives for paper coating compositions, as well as within paint formulations. Suspension-treated paper substrates are also encompassed within this invention, as is the method of producing such a unique suspension.
