Latest Patents

One of his latest patents is titled "Process for the production of granulates of organic substances present." This patent describes a method where the organic substance, in the form of a melt, is cooled below its solidification point in a twin-screw extruder. This process allows the material to crystallize out effectively. The crystallized material is then extruded through a breaker plate at the end of the screw extruder and further cooled. It is crucial that the temperature in the screw extruder, its rotational speed, and the temperature of the breaker plate are adjusted to ensure that between 70% to 99.5% of the material solidifies before reaching the end of the screw. The non-crystallized liquid residue crystallizes out during the subsequent cooling operation, allowing for a small residue of melt during extrusion through the breaker plate. Additionally, extrusion is facilitated if the breaker plate is maintained at a temperature near the melting point of the material.

Another significant patent by Muller is for the "Continuous solvent-free polymerization of vinyl derivatives." This process focuses on the polymerization of aromatic vinyl compounds and their copolymerization with alkyl esters or nitriles of acrylic and/or methacrylic acid.
