Patent

CA 2464086

The present invention relates to a method for post-modification of a macroporous polymeric support comprising one or more unreacted double bonds, which method includes the steps of contacting the support with a liquid comprising a grafting compound; and initiating a free radical reaction in the mixture obtained, wherein the grafting compound is comprised of a double bond as a re-active group coupled to a linear or cyclic chain of carbon. The grafting compound can be illustrated with vinyl ethers and/or styrene and styrene derivatives.

La présente invention concerne un procédé de post-modification d'un support polymère macroporeux comprenant au moins une double liaison ne présentant pas de réaction. Ce procédé consiste à mettre en contact le support avec un liquide contenant un composé de greffage et à initier une réaction de radical libre dans le mélange obtenu, le composé de greffage étant constitué d'une double liaison en tant que groupe réactif couplé à une chaîne de carbone linéaire ou cyclique. Le composé de greffage peut être illustré d'esters vinyliques et/ou de styrène et de dérivés de styrène.
