Latest Patents

One of Jean Chatelain's key patents is titled "Process for bulk polymerization." This patent describes a method for the bulk polymerization of monomers that produce polymers insoluble in the monomers. The process is carried out in an autoclave mounted on a horizontal axis, equipped with stirring means formed of at least two half-frames. These half-frames are arranged symmetrically around the axis of the autoclave and are fixed at each end to a rotatable stub shaft. Each half-frame features a peripheral member that acts as a blade, which, upon rotation, passes in close proximity to the interior surface of the autoclave. Additionally, bracing means interconnect the peripheral members of the half-frames. This innovative approach enhances the efficiency and effectiveness of polymer production.
