Title: Joanna L. Shih: Innovator in Glycerol-Based Polyols

Introduction

Joanna L. Shih is a prominent inventor based in Downers Grove, IL (US). She has made significant contributions to the field of glycerol-based polyols, holding 2 patents that showcase her innovative methods and applications.

Latest Patents

Her latest patents include the "Production and composition of glycerol based polyols" and "Glycerol based polymer surface active chemistry and production." The first patent provides a method for efficiently producing branched, cyclic glycerol-based polyols with a co-product that acts as an anti-biodegrading agent. This method involves polymerizing glycerol or glycerol with other monomers in the presence of a strong base catalyst under specific distillation conditions. The resulting polyol is beneficial for reducing scales in Bayer liquid during aluminum production and improving the brightness of coated paper substrates without causing a greening effect.

The second patent focuses on producing branched, cyclic glycerol-based polymer surface active products with ester and alkyl functional groups. This process also utilizes glycerol and other monomers, polymerized under similar conditions. The products produced are advantageous for reducing lignin, extractives, and rejects in the pulping process of the papermaking industry.
