Abstract

1484566 Polymer coated porous particles; coating apparatus T J SMITH & NEPHEW RESEARCH Ltd 22 July 1974 [26 July 1973] 35676/73 Headings B2E and B2L [Also in Division Cl] Porous absorptive particles, e.g. carbon or polystyrene are coated with a biocompatible polymer, e.g. polyhydroxyethylmethacrylate, cellulose acetate, polyurethane, silicone or polyamide, which hinders mechanical breakdown of the particles and provides a smooth permeable particle surface without plugging the pores. Up to 20%, preferably 0.5 to 5% of polymer may be used. A method for preparing such material comprises heating a mass of the particles while causing or allowing them to adopt relative motion and spraying the heater particles with a polymer solution. The solvent is allowed to evaporate. Apparatus for coating the particles, e.g. carbon granules 23, comprises means for holding the mass of porous absorptive material, e.g. rotary coating pan 21, while causing or allowing relative motion of the individual particles, a spray head 25 for supplying polymer solution to the mass and means to heat the mass, e.g. heated air from duct 24.
