Latest Patents

Hacene Mehalla's latest patents focus on a process for the on-line grafting of carboxylic acids. The process involves several key steps: (I) the (co)polymerization of ethylene is conducted in at least one reaction zone under high pressure, at temperatures ranging from 150°C to 320°C; (II) the reaction product is directed into a separation zone under intermediate pressure for the separation of the (co)polymer from unreacted (co)monomers; and (III) the (co)polymer is finally separated from residual gases in a low-pressure zone. This innovative approach includes the introduction of grafting monomers and initiators at various points along the polymer path, enhancing the efficiency of the grafting process.
