Publication number: 20180230259Abstract: The thermoplastic polyurethane compositions described herein have very good recovery properties, rebound resilience, or both, while also having good softness (i.e. low hardness). It has been difficult to provide thermoplastic polyurethane compositions with this combination of properties. Some compositions described herein also provide low haze and/or good clarity properties. These combination of properties make the thermoplastic polyurethane compositions described herein useful materials for application that require fast recovery, good rebound resilience, or both while also requiring soft materials, and in some embodiments low haze and/or good clarity.Type: ApplicationFiled: March 7, 2018Publication date: August 16, 2018Inventors: Joseph J.

Patent number: 9403303Abstract: The present invention discloses a thermoplastic polyurethane which is comprised of the reaction product of (1) a hydroxyl terminated polyester intermediate, (2) a polyisocyanate, and (3) a glycol chain extender; wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from 1,3-propylene glycol and a dicarboxylic acid; wherein the hydroxyl terminated polyester intermediate has a number average molecular weight from 500 to 10,000; and wherein the thermoplastic polyurethane includes hard segments that are the reaction product of the polyisocyanate and the glycol chain extender. This thermoplastic polyurethane is unique in that it has a greatly reduced tendency to bloom. This is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance.Type: GrantFiled: July 28, 2014Date of Patent: August 2, 2016Assignee: Lubrizol Advanced Materials, Inc.Inventors: Julius Farkas, Charles P. Jacobs

Patent number: 4841053Abstract: Certain polysubstituted piperazinones (PSP) having two or three methylene groups linking the N.sup.1 atom of the ring to the N atom of a terminal amine group, are found to be peculiarly prone to decomposition when subjected to elevated temperature after being contacted with water, and sensitive to the amount of base used in the base-induced ketoform reaction which generates the PSP represented by the structure ##STR1## These PSP are therefore produced by a modification of the ketoform reaction under essentially anhydrous conditions, using enough ketone to dissolve the PSP formed and a molar ratio of solid alkali metal hydroxide/diamine reactant in the range from at least 5 but less than 7. The PSP produced is recovered as a solution in the ketone, without contacting the PSP with water. The PSP product obtained after the ketone is distilled, is essentially pure.Type: GrantFiled: January 21, 1988Date of Patent: June 20, 1989Assignee: The B. F. Goodrich CompanyInventors: Pyong-Nae Son, Charles P. Jacobs, Ronald M. Kovach, John T. Lai
