Abstract
This invention discloses stable, aqueous polymeric dispersions comprised of at least 25% solids, dry basis, of a starch graft copolymer of a thinned and derivatized starch and at least one vinyl monomer. The starch has a degree of substitution of at least about 0.05 and an intrinsic viscosity of not less than about 0.12 deciliters per gram. The starch graft copolymers have a starch/monomer ratio of less than about 100/25. The dispersions are stable over extended periods of time at normal storage temperatures. Processes for the production of the dispersions are also disclosed.
