Latest Patents

Shannon's latest patents include groundbreaking inventions such as block copolymers of lactones and poly(propylene fumarate). This invention provides well-defined biodegradable poly(lactone-b-propylene fumarate) diblock and triblock polymers formed using a novel one-pot, scalable ring-opening block-order copolymerization (ROBOCOP) technique. This technique utilizes magnesium 2,6-di-tert-butyl-4-methylphenoxide (Mg(BHT)(THF)) to switch from the ROP of cyclic esters to the ROCOP of maleic anhydride (MAn) and propylene oxide (PO). The resulting PPF-based block copolymers are designed for applications in additive manufacturing and patient-specific regenerative medicine. These block copolymers are fully resorbable and can be photochemically crosslinked for various applications, including 3D printing. By incorporating the lactone block into the PPF polymer, the viscosity of the resulting block copolymer at working temperatures can be precisely controlled, allowing for a reduction or elimination of the reactive diluent in printable resins. Another significant patent involves the synthesis of Mg(BHT)(THF), which presents a novel method for synthesizing this catalyst. This method eliminates the need for dry toluene or pentane and allows for a one-step synthesis, reducing the time required for catalyst preparation.
