Patent

CA 2231091

A process for preparing anhydride polymers in aromatic hydrocarbon solvents using a dialkyl peroxide/amine compound initiator system is disclosed. The amine compound allows more efficient use of free-radical initiators while achieving high monomer conversion polymerizations compared to conventional initiator systems, particularly in the preparation of maleic anhydride polymers.

Processus de préparation de polymères d'anhydrides dans des solvants d'hydrocarbures aromatiques en utilisant un système d'initiateurs comportant un peroxyde dialcoylé et un composé aminé. Le composé aminé permet une utilisation plus efficace des initiateurs qui sont des radicaux libres, tout en obtenant une forte polymérisation par conversion de monomères comparativement aux systèmes d'initiateurs classiques, particulièrement dans la préparation de polymères de l'anhydride maléique.
