Latest Patents

Schmidt's latest patents include a method for the preparation of oligomeric alkylene terephthalates. This innovative process involves passing dimethylterephthalate and a diol with at least three carbon atoms through a series of reaction chambers. Each chamber is equipped with stirring and heating means, allowing the temperature to increase progressively. This method effectively facilitates transesterification while ensuring that the methanol evolved is vented without mixing with the transesterification material. The resulting oligomers exhibit high reactivity, simplifying their further condensation into polyesters.

Another significant patent focuses on the preparation of polycondensates through a one-step melt condensation in a vacuum. This method improves the production of linear polycondensates of high molecular weight. It involves forming a precondensate that is subjected to melt condensation while removing cleavage products. The process is optimized by continuously introducing a molten precondensate into the condensation zone, ensuring efficient production of high-quality polycondensates.
