Title: Frank E Livingston: Innovator in Polyurethane Technology
Introduction
Frank E Livingston is a notable inventor based in Wilmington, DE (US). He has made significant contributions to the field of polyurethane technology, holding 2 patents that showcase his innovative approach to utilizing waste streams in chemical processes.
Latest Patents
Livingston's latest patents include groundbreaking work on polyurethane foams derived from polyester precursors. One of his patents focuses on the recovery of a waste stream of non-volatiles (NVR) as a by-product from the oxidation of cyclohexane to cyclohexanone and cyclohexanol in the production of adipic acid. This NVR is partially dehydrated and reacted with an esterifying polyol to create a polyester polyol product, which is essential for producing high-quality polyurethane foams. A particularly noteworthy end-product is a rigid polyurethane foam that exhibits excellent cell structure and a density of at least 2.0 lb./cu. ft.
Another patent addresses the development of a polyester plasticizer for vinyl resins, also derived from the adipic acid process. In this case, the NVR is dehydrated and reacted with an esterifying polyol to form a polyester polyol that effectively disperses vinyl resins. Polyester polyols with low acid numbers, particularly those under 10 and preferably under 2, have been found to be the most effective as vinyl dispersion plasticizers. The resulting end-products include tough vinyl resin films with a Shore A hardness of approximately 55, which can also be utilized in wire coatings and coverings.
