Publication number: 20230286964Abstract: A series of bio-based benzoxazine monomers were developed. These benzoxazine monomers are liquid at room temperature with good processability due to their low viscosities at or near room temperature and their relatively low polymerization temperatures. Cured materials made from these bio-based benzoxazines have excellent thermal and mechanical properties.Type: ApplicationFiled: July 23, 2021Publication date: September 14, 2023Applicants: DREXEL UNIVERISTY, The United States of America as Represented by the Secretary of the ArmyInventors: Giuseppe Raffaello Palmese, Mengwen Yu, John Joseph La Scala

Patent number: 11718629Abstract: This invention outlines a method for synthesizing a blended resin system in a one pot reaction that may utilize, for example, bio-based anhydrosugars such as isosorbide as a principle component to produce isosorbide dimethacrylate and other monomeric materials for thermosetting applications. This invention establishes a one-pot procedure for reacting a hydroxy group containing compound with methacrylic anhydride in the first step and using the by-product methacrylic acid to react with glycidyl ethers to form additional methacrylate compounds in the second step. This methodology can be formulated to produce a wide array of resin systems that have controlled ratios of hydroxy group containing compound/cross-linker/reactive diluent. Additionally, the novel resin systems may be partially to fully bio-based, promoting global sustainability and reducing costs, and when free radically polymerized have properties that meet or exceed their petroleum derived counterparts.Type: GrantFiled: November 18, 2021Date of Patent: August 8, 2023Assignees: Drexel University, The United States of America as Represented by the Secretary of the ArmyInventors: Joshua Matthew Sadler, John Joseph La Scala, Giuseppe R.

Publication number: 20210380567Abstract: A composition of matter including two optionally substituted phenol or optionally substituted aniline units separated by a furan spacer has been prepared. In particular, the chemical structure has a novolac bridge between the central furan ring and the two attached optionally substituted phenol and/or optionally substituted aniline units. These compounds can be modified to be used in various polymer resins. This new structure reduces toxicity relative to BPA/F, makes use of renewable chemicals, and produces certain beneficial polymer properties.Type: ApplicationFiled: October 10, 2019Publication date: December 9, 2021Applicants: Drexel University, The Government of the United States, as represented by the Secretary of the Army, Rowan UniversityInventors: Craig Michael PAQUETTE, John Joseph LA SCALA, Joshua Matthew SADLER, Giuseppe Rafaello PALMESE, Alexander William BASSETT, Joseph Francis STANZIONE

Publication number: 20200148827Abstract: A family of new and novel molecules for mechanically superior two-dimensional (2D) polymers is described herein. By combining stiff carbon-containing cyclic polymer nodal units with more compliant linear polymer bridge units in an ordered, 2D repeating molecular structure it is possible to tailor the mechanical properties of 2D polymers and their assemblies to provide high stiffness, strength, and toughness. Furthermore, the inherent dimensionality of 2D polymers and their ability to be stacked into ordered and chemically interactive ensembles gives them inherent benefits in a variety of barrier and structural applications over current stiff and strong linear polymer technologies.Type: ApplicationFiled: January 16, 2020Publication date: May 14, 2020Inventors: Eric D. Wetzel, Emil Jose Sandoz-Rosado, Todd David Beaudet, Radhakrishnan Balu, John Joseph La Scala, Dominika Nini Lastovickova

Patent number: RE43983Abstract: Multi-modal vinyl ester resins having one or more of good fracture toughness, good processing viscosity, and low volatile organic compound emissions are provided. The multi-modal vinyl ester resins are the reaction product of a liquid or crystalline epoxy and an amorphous, solid epoxy, as determined at 25° C., with a vinyl carboxylic acid. The multi-modal vinyl ester resins may contain a reactive diluent, though generally, lower reactive diluent contents are required for such resins than for similar, commercially available vinyl ester resins.Type: GrantFiled: May 6, 2005Date of Patent: February 5, 2013Assignees: Drexel University, The United States of America as Represented by the Secretary of the ArmyInventors: Giuseppe Raffaello Palmese, John Joseph La Scala, James Matthew Sands
