The present invention relates to a cross-linked polyether which is obtained by polymerization of at least one monomer selected from the group consisting of (a) (.alpha.-X-methyl) vinyl-EWG, (.alpha.-X-methyl) vinyl-ERG, or (.alpha.-X- methyl) vinyl-aryl, where X is oxygen, sulfur, PEG, PPG or poly (THF); (b) a monomer which is polymerizable with a PEG, PPG or poly (THF) cross-linker having at least one (.alpha.-X-methyl) vinyl-EWG, (.alpha.-X-methyl) vinyl-ERG or (.alpha.-X-methyl) vinyl-aryl, where X is oxygen, sulfur, PEG, PPG, or poly (THF); (c) a PEG, PPG, or poly (THF) cross-linker having at least an acrylamide or a methacrylamide end group; and (d) mixtures thereof. Various monomers, resins and methods for preparing such cross-linked polyethers are also disclosed.
L'invention concerne un polyéther fortement réticulé obtenu par polymérisation d'au moins un monomère choisi dans le groupe se composant de : (a) (a-X-méthyl)vinyl-EWG, (a-X-méhyl)vinyl-ERG, ou (a-X-méthyl)vinyl-aryle, X représentant oxygène, soufre, PEG, PPG ou poly (THF); (b) un monomère polymérisable avec un réticulant PEG, PPG ou poly (THF) possédant au moins un (a-X-méthyl) vinyl-EWG, (a-X-méthyl) vinyl-ERG ou (a-X-méthyl)vinyl-aryle, X représentant oxygène, soufre, PEG, PPG, or poly (THF); (c) un réticulant PEG, PPG, ou poly (THF) possédant au moins un acrylamide ou un groupe terminal méthacrylamide, et (d) des mélanges de ceux-ci. Divers monomères, résines et procédés de préparation desdits polyéthers réticulés sont également décrits.
