Latest Patents

Freeman's latest patents include innovative solutions in polymer chemistry. One of his notable inventions is related to copolymers of zwitterionic monomers, particularly 2-methacryloyloxyethyl-2'-trimethylammoniumethyl phosphate inner salt, combined with hydrophobic comonomers like dodecylmethacrylate. This invention utilizes a monomer starved polymerization process, where solutions of monomers are gradually fed into a reaction vessel containing an initiator. The resulting copolymers exhibit improved compositional uniformity and provide enhanced coatings on various substrates. These novel copolymers can be distinguished from traditional batch-type bulk solution polymerization polymers by their solubility characteristics, especially in alcohol/water mixtures. Preferred coating compositions consist of an alcohol:water mixture containing approximately 20 to 40% by volume alcohol.

Another significant patent involves anion exchange materials and processes. In this invention, the surfaces of anion exchange materials are treated with zwitterionic and cationic groups, typically through a polymer coating formed from a combination of zwitterionic and cationic monomers. This technology allows for the scavenging of heparin from blood using an ion exchange separation process, while the zwitterionic group helps reduce fouling by biological materials such as proteins.
