Title: Gregory R. Hahn: Innovator in Plasticizer Technology
Introduction
Gregory R. Hahn is a notable inventor based in Corpus Christi, TX (US). He has made significant contributions to the field of polymer science, particularly in the development of advanced plasticizers. With a total of 5 patents to his name, Hahn's work has had a considerable impact on the industry.
Latest Patents
Hahn's latest patents focus on the use of lower alkyl biphenyls as plasticizers for polyurethane. His innovative approach involves a polymer containing a di-, tri-, and/or tetra-ethyl-, propyl- and/or butylbiphenyl plasticizer, which constitutes the major proportion by weight of any other plasticizing or softening additive. This composition is particularly effective when the polymer is not polyvinyl chloride. When dealing with elastomers or rubbers, or polystyrene, the plasticizer used is diisopropylbiphenyl and/or triisopropylbiphenyl. Furthermore, his method for preparing the plasticizer-polymer composition includes mixing a monomer and/or oligomer component with the plasticizer to create a uniform mixture, which can then undergo further processing. This method allows for high loading levels of the plasticizer without compromising the properties of the plasticized polymer, representing a significant advancement over prior art plasticizing additives.
