Patent

CA 2690706

There are provided poly(vinyl alcohol) polymers and copolymers containing vinyl alcohol or vinyl acetate and derivatives thereof such as poly(ethylene glycol)-grafted poly(vinyl alcohol) polymers or polyether-grafted poly(vinyl alcohol) polymers. These polymers can contain various functional groups. Such polymers can be use as polymer matrix or solid support for various chemical substrates such as organic substrates and reagents. Cross-linked poly(vinyl alcohol) polymers and copolymers are also provided. Methods for preparing such polymers as well as several of their uses are also included.

L'invention concerne des polymères poly (alcool vinylique) et des copolymères contenant de l'alcool vinylique ou de l'acétate de vinyle et leurs dérivés, tels que les polymères alcools polyvinyliques greffés par du poly (éthylène glycol) ou des poly (alcool vinylique) polymères greffés par du polyéther. Ces polymères peuvent contenir divers groupes fonctionnels. De tels polymères peuvent être utilisés comme matrice ou support solide polymère pour divers substrats chimiques tels que des substrats organiques et des réactifs. Des polymères et copolymères poly (alcool vinylique) réticulés sont également proposés. Des procédés pour préparer de tels polymères ainsi que plusieurs de leurs utilisations sont également inclus.
