Title: The Innovations of Matthew I Levinson

Introduction

Matthew I Levinson is a notable inventor based in Skokie, IL (US). He has made significant contributions to the field of chemistry, particularly in the development of antiplasticizers for thermoplastic polyesters. With a total of 9 patents to his name, Levinson's work has had a considerable impact on material science.

Latest Patents

One of Levinson's latest patents involves the preparation of antiplasticizers for thermoplastic polyesters. This process includes the reaction of dimethyl terephthalate with an excess of aryloxyalkanol in the presence of a condensation catalyst. The result is an intermediate mixture that contains bis(aryloxyalkyl)terephthalate, mono(aryloxyalkyl)terephthalate, and unreacted aryloxyalkanol. The mixture continues to react at reduced pressure while unreacted aryloxyalkanol is removed, ensuring that the mono-ester content is reduced to less than 1 mole % based on the combined amounts of mono- and bis-esters. Both steps are performed substantially in the absence of oxygen. The final product is a purified bis(aryloxyalkyl)terephthalate with an overall purity of at least 98 mole % and a yellowness index of less than 10. This careful control over catalysis and process conditions allows for high yields of bis(aryloxyalkyl)terephthalates that possess low color and other valuable attributes.
