Title: Bernd Gemmel: Innovator in Polytrimethylene Terephthalate Resins
Introduction
Bernd Gemmel is a notable inventor based in Gelnhausen, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the development of Polytrimethylene Terephthalate (PTT) resins. With a total of 2 patents to his name, Gemmel's work focuses on improving the properties of these resins, making them more efficient and environmentally friendly.
Latest Patents
Gemmel's latest patents revolve around the formulation of PTT resins with reduced emissions of acrolein. The first patent describes a composition that involves contacting PTT resin with a melt-stable, organic stabilizing compound. This innovative approach results in a PTT resin that has an acrolein formation rate of less than 15 ppm/minute at 280°C, with a residual acrolein content of less than 10 ppm. The preferred stabilizing compounds are free from nitrogen atoms and include polyfunctional alcohols, alcoholates, and aromatic carboxylic acid anhydrides. The second patent similarly addresses the emission of acrolein but utilizes a melt-unstable, organic nitrogen-containing stabilizing compound. This formulation achieves an acrolein formation rate of less than 15 ppm/minute, with a residual acrolein content of less than 5 ppm. The additive compounds in this case include amines, amino acids, and urea.
