Latest Patents

Widdifield holds a patent for a method that enhances colloidal stability in polyvinyl chloride. This patent describes a process where a monomer slurry is created by mixing monomers with water in a reaction vessel. The slurry is then heated to the reaction temperature. After a delay of 0 to 15 minutes, an emulsifier package is introduced, followed by a catalyst emulsion after another delay. The emulsifier package includes a primary emulsifier, which is partially saponified polyvinyl alcohol, and a secondary cellulosic emulsifier. The resulting polymerization product exhibits excellent bulk density and porosity, with resins that demonstrate low fisheye characteristics.
