摘要: A process for preparing free standing polymeric belts which includes the steps of providing at least one sleeve electrode coaxially spaced apart from and surrounding at least one other electrode in a bath comprising a dispersion of electrically charged, thermoplastic film forming polymer particles in an organic liquid dispersion medium, the polymer particles having a weight average molecular weight of at least about 35,000 and being substantially insoluble in the organic liquid medium at electrodeposition temperatures and sufficiently soluble in the organic liquid medium at elevated temperatures to coalesce and form a viscous sol coating, applying an electric field across the electrodes until a thick, substantially uniform deposit of polymer particles forms on the interior surface of the sleeve electrode, removing the sleeve electrode bearing the deposit of polymer particles and residual liquid dispersion medium clinging to the deposit of polymer particles from the bath, heating the deposit to initially solubilize the polymer particles in the residual organic liquid dispersion medium to form a coalesced, continuous viscous sol coating of the solubilized polymer particles, continuing the heating to evaporate the residual organic liquid dispersion medium and form a continuous, solidified, cylindrical, dry polymer film, and removing the dry polymer film from the interior surface of the sleeve electrode. This dry polymer film may subsequently be coated with various layers.

摘要: A process is disclosed for forming at least one thin substantially uniform fluid coating comprising polymeric film forming material on a cylindrical mandrel, solidifying the fluid coating to form a uniform solid coating and separating the uniform solid coating from the mandrel. The process may comprise forming at least one thin substantially uniform fluid coating comprising polymeric film forming material around a cylindrical mandrel, the mandrel having a larger mass or lower thermal conductivity than the polymeric film forming material and a critical surface tension greater than the surface tension of the fluid coating, solidifying the fluid coating to form at least one thin substantially uniform solid coating comprising the polymeric film forming material around the cylindrical mandrel, heating both the uniform solid coating and the mandrel to a temperature at least above the apparent T.sub.g of the solid coating to expand the coating and the mandrel while maintaining contact between the coating and the mandrel, cooling the coating to below the apparent T.sub.g of the solid coating prior to substantial cooling of the mandrel, and cooling the mandrel whereby the mandrel contracts at a greater rate than the polymeric coating until separation occurs between the mandrel and the coating, and removing the coating from the mandrel.
