Patent number: 10273339Abstract: Porous networks are described linked by boronates. Also described are processes for producing the porous networks. The porous networks are formed by reacting a polyboronic acid with itself or with a polydiol, a polydiamine, or a polyamino alcohol. The resulting boronate linkage is covalently bonded. The characteristics and properties of the resulting porous material can be varied and altered by changing the reactants and by incorporating functional groups into the reactants. Of particular advantage, the porous materials can be formed at or near atmospheric pressure and at low temperature in the presence of one or more solvents.Type: GrantFiled: September 8, 2014Date of Patent: April 30, 2019Assignee: University of South CarolinaInventors: John J.

Publication number: 20140364523Abstract: This invention relates to viscoelastic silicone rubber compositions that are the products of the reaction of: (a) a silanol-terminated polyorganosiloxane base; (b) a boron-containing crosslinking agent; and (c) a siloxane bond-forming crosslinking agent. In a viscoelastic silicone rubber composition of the invention some of the crosslinks, the siloxane crosslinks, are permanent and others of the crosslinks, the boron-containing crosslinks, are temporary. Because a fraction of its crosslinks can come apart and then reform, a viscoelastic silicone rubber composition of the invention can relax stress in response to strain and thus adapt to new shapes. The composition has sufficient permanent crosslinks, however, to establish a permanent equilibrium shape to which the composition will eventually return when not subject to any imposed stress.Type: ApplicationFiled: July 21, 2014Publication date: December 11, 2014Applicant: UNIVERSITY OF VIRGINIA PATENT FOUNDATIONInventor: Louis A.

Patent number: 6472443Abstract: Highly crosslinked monolithic porous polymer materials for chromatographic applications. By using solvent compositions that provide not only for polymerization of acrylate monomers in such a fashion that a porous polymer network is formed prior to phase separation but also for exchanging the polymerization solvent for a running buffer using electroosmotic flow, the need for high pressure purging is eliminated. The polymer materials have been shown to be an effective capillary electrochromatographic separations medium at lower field strengths than conventional polymer media. Further, because of their highly crosslinked nature these polymer materials are structurally stable in a wide range of organic and aqueous solvents and over a pH range of 2-12.Type: GrantFiled: June 22, 2000Date of Patent: October 29, 2002Assignee: Sandia National LaboratoriesInventor: Timothy J.

Patent number: 5516810Abstract: Unimolecular micelles, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Reactive sites located on the framework and hence within the void regions are capable of being chemically transformed to allow covalent and noncovalent incorporation of one or more guest species into the said void regions. Further, a method is described for making such cascade polymers that includes the steps of forming a unimolecular micelle containing internal void areas with accessible reactive sites capable of bonding to at least one guest after construction of the said unimolecular micelle. The guests are contained within the internal void volume of the cascade polymer and are available and accessible for additional chemical modification.Type: GrantFiled: February 14, 1994Date of Patent: May 14, 1996Assignee: University of South FloridaInventors: George R.

Polymer foams with inherent nonflammability and thermal stability and methods of preparation thereof
Patent number: 5514726Abstract: Polymeric foams with novel chemical compositions are prepared by the condensation of specially-synthesized precursors, which contain (in addition to carbon and hydrogen) one or more of the following elements: oxygen, fluorine, nitrogen (in structures with stable chemical bonds), silicon, boron, phosphorus (in high oxidation states), and certain metals (and/or their oxides and hydroxides). Upon mixing in the proper proportions and/or heating these precursors react rapidly to generate polymeric networks, consisting of heterocyclic crosslink centers, connected with heterochain segments; hydrogen is largely eliminated or replaced by fluorine. These structures possess inherent nonflammability and high thermoxidative stability. Foaming is effected by the gaseous by-products of the condensation reactions, as well as by the addition of foaming agents. The resulting foam products can be formulated to have a wide range of densities and flexibilities.Type: GrantFiled: September 15, 1992Date of Patent: May 7, 1996Inventors: Gus Nichols, C. D.
