Title: Innovations of Jean M Tancrede in Adhesive Compositions
Introduction
Jean M Tancrede is a prominent inventor based in Baton Rouge, LA (US), known for her significant contributions to the field of adhesive compositions. With a total of 17 patents to her name, she has made remarkable advancements in the packaging industry through her innovative work.
Latest Patents
Among her latest patents, Tancrede has developed polyolefin adhesive compositions that are composed of a polyolefin mixture containing at least 50 wt. % polypropylene and at least one wax. These polymer compositions exhibit a Dot T-Peel of about 1 Newton or more, a branching index (g') of 0.95 or less measured at the Mz of the polymer, and a molecular weight of 100,000 or less. The adhesive compositions are designed to have a fast set time, setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi-solid state. This innovation provides a favorable alternative to conventional formulated adhesives, offering a balance of high adhesive strength, a wide temperature operating window, and rapid setting capabilities.
Another notable patent involves polypropylene-based adhesive compositions, which include a semi-crystalline copolymer of propylene and at least one comonomer, such as ethylene. This copolymer has a weight average molecular weight (Mw) ranging from about 15,000 to about 200,000 and a melt index (MI) from about 7 dg/min to about 3000 dg/min, as measured by ASTM D 1238 (B). The patent also describes various production processes and methods for creating adhesive compositions with melt flow rates (MFRS) equal to and above 250 dg/min at 230°C.
