Latest Patents: Two of Stevens' latest patents demonstrate his expertise in polymer technology and environmental management. The first patent, titled "Direct application of surface treatment to absorbent polymers," details a novel method for preparing fluid absorbent polymers. This process involves the polymerization of ethylenically unsaturated monomer droplets in an inert organic phase containing a hydrophobic suspending agent. By blending the resulting hydrophobic polymer particles with a hydrophilic material without the use of organic solvents, Stevens' innovation effectively alters the surface properties, making them hydrophilic.

The second patent, "In situ solidification of ion exchange beads," outlines a method for encapsulating and solidifying spent ion exchange beads. This process eliminates the need for external shear forces, allowing the solidification resin to flow through the ion exchange bed via plug flow. The resin encapsulates the beads and cures to form a uniform solidified monolith. This innovative technique not only solidifies the beads but also removes substantial free water, enhancing the efficiency of ion exchange processes.
