Title: **James Keith Bardman: A Pioneer of Polymer Innovations**
Introduction
James Keith Bardman, a prolific inventor based in Green Lane, Pennsylvania, holds an impressive portfolio of 25 patents in the field of polymer technology. His innovations have significantly advanced the manufacturing processes and applications of polymeric materials.
Latest Patents
Among his latest patents, Bardman developed an **Aqueous Dispersion of Multistage Polymer Particles**. This invention details a composition that includes an aqueous dispersion featuring multistage polymer particles with distinct phases. The first phase consists of structural units from a carboxylic acid monomer or its salt, combined with a nonionic ethylenically unsaturated monomer. The second phase is characterized by two polymers, where either one or both incorporate structural units of a high hydrophobic monomer, such as cyclohexyl methacrylate or t-butylstyrene. Notably, these multistage polymer particles serve as opaque polymers in pigmented coating formulations, showing exceptional collapse resistance and low dry bulk density without requiring acrylonitrile.
Another significant contribution from Bardman is the **Preparation of a Coatings Formulation with Alkali Swellable Polymer Particles**. This process involves creating a coatings composition with a volatile organic compound (VOC) content of less than 50 g/L by utilizing swelled polymer particles that result from the neutralization of alkali swellable polymer particles. This innovative formulation is particularly beneficial for improving open time in low VOC coating applications.
