Patent number: 9926399Abstract: An elastomeric polymer, comprising (1) a hard segment in the amount of 10% to 60% by weight of the elastomeric polymer, wherein the hard segment includes a urethane, urea, or urethaneurea; and (2) a soft segment in the amount of 40% to 90% by weight of the elastomeric polymer, wherein the soft segment includes a polyisobutylene macrodiol and/or diamine. Additionally disclosed is a method of forming a polyisobutylene-based thermoplastic urethane, comprising the steps of (a) reacting a polyisobutylene macrodiol and/or diamine with a diisocyanate to form a first reaction mixture; (b) combining a metal catalyst and a chain extender with the first reaction mixture to create a second reaction mixture, a molar ratio of the metal catalyst to the diisocyanate being greater than 0.0:1 and less than or equal to 0.4:1; and (c) reacting the second reaction mixture for a period of time sufficient to form the polyisobutylene-based thermoplastic urethane.Type: GrantFiled: November 21, 2013Date of Patent: March 27, 2018Assignee: University of MassachusettsInventors: Rudolf Faust, Xinyu Wei

Patent number: 9926401Abstract: Methods for making wet gels and dried gels therefrom are provided. The method for making a wet gel can include combining a hydroxybenzene compound, an aldehyde compound, and an additive to produce a reaction mixture. The additive can include a carboxylic acid, an anhydride, a homopolymer, a copolymer, or any mixture thereof. At least the hydroxybenzene compound and the aldehyde compound can be reacted to produce a wet gel. The reaction mixture can include about 10 wt % to about 65 wt % of the hydroxybenzene compound, about 5 wt % to about 25 wt % of the aldehyde compound, up to about 85 wt % of the carboxylic acid, up to about 40 wt % of the anhydride, up to about 40 wt % of the homopolymer, and up to about 40 wt % of the copolymer, where weight percent values are based on the combined weight of the hydroxybenzene compound, the aldehyde compound, and the additive.Type: GrantFiled: March 17, 2017Date of Patent: March 27, 2018Assignee: Georgia-Pacific Chemicals LLCInventors: Xing Dong, Shahid P. Qureshi, Christopher M. Lee, Kelly A. Shoemake, Joseph Frank Ludvik
