Title: Thomas Gädda: Innovator in Glycolic Acid Polymers
Introduction
Thomas Gädda is a notable inventor based in Espoo, Finland. He has made significant contributions to the field of polymer chemistry, particularly in the production of glycolic acid polymers. With a total of 5 patents to his name, his work has paved the way for more efficient and economically feasible methods in polymer production.
Latest Patents
One of Gädda's latest patents is a method of producing glycolic acid polymers. This invention describes a feasible and significantly simplified production method that avoids challenging lactonization steps. It converts a low molecular weight aliphatic polyester, consisting of hydroxy acids and a comonomer, whose molecular weight has been increased by step-growth polymerization reactions. The molecular weight of the aliphatic polyester increases significantly at a rate that permits the use of reactive extrusion to produce high molecular weight aliphatic polyesters in a simple and economically feasible manner.
Another significant patent is the method for preparing glycolide polyester by ring opening polymerization. This invention relates to a method for preparing a glycolide polyester characterized by subjecting glycolide monomer with optional co-monomer(s) of cyclic ester(s) to ring opening polymerization in the presence of a dispersion stabilizer and a catalyst. The catalyst is selected for precipitating glycolide homopolymer or copolymer from solvent, ensuring that the glycolide monomer and the optional co-monomer(s), the dispersion stabilizer, and the catalyst are soluble, while the glycolide homopolymer or copolymer remains non-soluble.
