Latest Patents
Johann Jelen's latest patents focus on innovative processes for the preparation of chlorinated polymers. The first patent describes a method for chlorinating chlorine-free polymers using gaseous chlorine in chlorinated hydrocarbons as solvents. This process allows for the recovery of chlorinated aliphatic polymers through steam distillation, with the addition of 15 to 50% by weight of a lacquer resin to enhance the efficiency of the process. The resulting chlorinated polymers exhibit reduced residual solvent content. The second patent outlines a similar process, emphasizing the use of a chlorinated hydrocarbon solvent and the incorporation of 2 to 25% by weight of a plasticizer or lacquer resin during chlorination. This method also culminates in the isolation of the chlorinated aliphatic polymer via steam distillation.
