Latest Patents

One of Smith's latest patents is titled "Interfacial preparation of polycarbonate prepolymer with motionless mixer." This innovative process involves the production of polycarbonate prepolymers by combining phosgene, dihydric phenols, halogenated organic solvents, and aqueous caustic solutions. The use of motionless mixers allows for the formation of fine dispersions of partially phosgenated phenols, facilitating interfacial reactions that lead to high molecular weight prepolymers. These prepolymers can then be polymerized with amines to create high molecular weight polycarbonates.

Another significant patent is "Preparation of additive modified thermoplastic blend." In this patent, Smith describes a method for preparing additive modified blends of thermoplastic resins. This process involves combining rubber modified polycarbonate or aromatic polyester carbonate concentrate resin with a let-down resin and/or regrind resin, resulting in enhanced material properties.
