Patent number: 9907815Abstract: A method for the polymerization of ?-lipoic acid and ?-lipoic acid derivatives includes preparing an ?-lipoic formulation, exposing the ?-lipoic formulation to an aqueous phase and a gaseous phase at a gas/water interface, and allowing the ?-lipoic formulation to polymerize at the gas/water interface to form a poly(?-lipoic acid) polymer. The ?-lipoic formulation can be an ?-lipoic solution of an ?-lipoic solute and an organic solvent miscible with water, and can also be an ?-lipoic acid or oligomer or polymer thereof in liquid (typically melt) form.Type: GrantFiled: November 21, 2014Date of Patent: March 6, 2018Assignee: The University of AkronInventors: Judit E.

Patent number: 9885070Abstract: The invention relates to functionalized, telechelic polymers synthesized by enzymatic catalysis and methods, and the functionalization of polymers via Michael addition with a lipase catalyst, and the crosslinking of mono- or difunctional (telechelic) polymers made by enzymatic catalysis, such as by using multifunctional coupling agents and enzyme catalysts. Quantitative transesterification of vinyl methacrylate with poly(ethylene glycol), poly(isobutylene) and poly(dimethylsiloxane) was achieved using Candida antarctica lipase B. In addition, methacrylate-functionalized poly(ethylene glycol) monomethyl ether has been successfully coupled to aminoethoxy poly(ethylene glycol) monomethyl ether via Michael addition using Candida antarctica lipase B. Amine-functionalized poly(ethylene glycol)s have also been used for the preparation of poly(ethylene glycol)-based dendrimers and gels through Michael addition of the polymer onto triacryloyl hexahydro-triazine using the same enzyme.Type: GrantFiled: April 3, 2014Date of Patent: February 6, 2018Assignee: The University of AkronInventors: Judit E Puskas, Mustafa Yasin Sen

Patent number: 9193680Abstract: High molecular weight disulfide polymers are synthesized in aqueous media by exposing dithiol compounds to a mild oxidizing environment in the presence of a tertiary amine catalyst. The unique oxidizing system polymerizes monomers through the formation of sulfur-sulfur bonds between dithiol compounds. The same oxidizing system may be used to make disulfide-crosslinked gels from compounds containing multiple thiol groups. The oxidizing system is comprised of oxygen at atmospheric concentration and dilute hydrogen peroxide. A filler such as carbon black may be incorporated into the polymer or cross-linked gel during polymerization. A polydisulfide polymer is provided having a weight average molecular weight of greater than about 100,000 g/mol and a polydispersity index of about 2 or less. A tetrathiol composition results from a reaction of a diacrylate with a trithiol.Type: GrantFiled: September 3, 2013Date of Patent: November 24, 2015Assignee: The University of AkronInventors: Judit E.
