Title: Innovations of Timothy D Shaffer
Introduction
Timothy D Shaffer is a notable inventor based in Voorheesville, NY (US). He has made significant contributions to the field of polyphenylene ether processes and resin compositions. With a total of 4 patents to his name, Shaffer's work has had a considerable impact on the development of thermoplastic materials.
Latest Patents
Shaffer's latest patents include innovative processes for producing polyphenylene ether. One of his inventions involves subjecting a 2,6-disubstituted phenol to oxidative coupling by introducing oxygen in the presence of a catalyst system. This system comprises a manganese compound, a chelant, a base, and an alpha,beta-unsaturated ketone, a beta-diketone, or a vinyl ether. The resulting polyphenylene oxide produced has substantially no amine odor and a more stable molecular weight. This makes it suitable for blending with styrenic or other resins to create thermoplastic resin blends with low odor and excellent physical properties. Another patent focuses on producing polyphenylene ether by subjecting a 2,6-dialkyl-4-halophenol to oxygen in the presence of a water-immiscible solvent, an aqueous alkali, a phase transfer agent, and a molecular-weight-controlling amount of an amine. The polyphenylene ether produced through this method exhibits improved flow properties, color, and odor, making it ideal for polymer blending with styrenic resins.
