Latest Patents

Yongjun Shin holds a patent for "Poly(propylene fumarate)-based copolymers for 3D printing applications." This invention is directed towards a PPF-based copolymer that is suitable for 3D printing. The copolymers exhibit a viscosity within a printable range and allow for light transmittance at curing wavelengths. Notably, lower viscosity copolymers can be achieved by substituting a portion of maleic anhydride with succinic anhydride. This results in the formation of a poly(propylene fumarate-co-succinate) copolymer through the copolymerization of maleic anhydride and succinic anhydride with propylene oxide via Mg(BHT)(THF) catalyzed ring opening copolymerization (ROCOP). These advancements enable the production of 3D printing resins that require less diethyl fumarate (DEF) while maintaining adjustable mechanical properties.
