Publication number: 20240010786Abstract: Disclosed is a polyol composition comprising: (a) at least one monomeric polyol comprising three or more hydroxyl groups; (b) at least one higher polyol comprising three or more hydroxyl groups; and (c) at least one polyhydroxylated aromatic compound; wherein the at least one higher polyol comprises residues of either or both of the at least one monomeric polyol and the polyhydroxylated aromatic compound linked by one or more carbonate groups, oxygen ether groups, or a combination thereof, and wherein the polyol composition has a viscosity of less than 5000 cps at 150 degrees Fahrenheit. The at least one monomeric polyol and at least one higher polyol may have any structures affording polyol compositions and polyurethane compositions having the requisite physical characteristics in terms of polyol composition viscosity and polyurethane heat resistance, strength and flexural modulus.Type: ApplicationFiled: October 21, 2019Publication date: January 11, 2024Inventors: Andrew John Tennant, James Henry Blumsom, Gary Jialanella, Jason Carter, James A.

Publication number: 20230002540Abstract: Disclosed are low-viscosity foamable polyurethane-forming compositions containing a polyol composition having monomeric and higher polyol components and optionally a polyhydroxylated aromatic compound; a polyisocyanate or latent polyisocyanate component or a combination thereof; a blowing agent; and optionally a cyclic carbonate having one or more hydroxyl groups. The monomeric and higher polyols each contain three or more hydroxyl groups, the higher polyol containing residues of the monomeric polyol and optionally residues of the polyhydroxylated aromatic compound, the residues being linked by one or more carbonate and/or ether groups. The Disclosed foamable polyurethane-forming compositions may contain the polyol compositions disclosed; an isocyanate functional component; and a blowing agent. The foamable compositions afford high strength, heat-resistant, low to moderate density foamed-polyurethane compositions useful in a variety of applications including construction, vehicle and packaging applications.Type: ApplicationFiled: November 23, 2020Publication date: January 5, 2023Inventors: Brett Tyler Sherren, Benjamin G.

Patent number: 11078325Abstract: There is provided an oligomeric polyol composition having (a) an oligomeric network containing residues of at least one polyhydroxylated aromatic compound and residues of at least one polyol having at least three hydroxyl groups; and (b) a plurality of peripheral groups having one or more pendant hydroxyl groups bound to the oligomeric network by a plurality of linking units. The residues of the polyol may optionally contain one or more oxygen ether groups, one or more amino ether groups, or both of one or more oxygen ether groups and one or more amino ether groups. Reaction of the oligomeric polyols with isocyanate monomers affords a new class of polyurethanes having superior heat and water resistance. The new polyurethanes exhibit lower peak exotherms, typically less than 250° F. during in-mold polymerization.Type: GrantFiled: August 20, 2018Date of Patent: August 3, 2021Assignee: Presidium USA, IncInventors: James Henry Blumsom, Andrew John Tennant, James A. Cella, David Goldwasser, Daniel J. Brunelle, Stephen Burks, Richard Heggs
