  • Process of making microparticles of a thermally-gelled polysaccharide
    Patent number: 6248268
    Abstract: Polymer microparticles suitable for gel chromatography are formed by spraying a composition of a thermally-gelling polymer in an aqueous medium into ambient air and allowing the atomized composition to gel in the air. The gelled microparticles have a gel strength sufficient to preserve the structural integrity of the gelled microparticle upon collection thereof.
