CA 2735880

The present invention relates to a (meth)acrylate monomer of the general formula (I) Image in which R1 is hydrogen or a methyl group, X is oxygen or a group of the formula NR' in which R' is hydrogen or a radical having 1 to 6 carbon atoms, R2 is an alkylene group having 1 to 22 carbon atoms, Y is oxygen, sulphur or a group of the formula NR", in which R" represents hydrogen or a radical having 1 to 6 carbon atoms, and R3 is an unsaturated radical having 8 carbon atoms and at least two double bonds. The present invention further relates to a process for preparing the monomers set out above, to polymers obtainable from this monomer mixture, and to coating materials which comprise the stated polymers.

La présente invention concerne un monomère de (méth)acrylate de formule générale (I), dans laquelle R1 représente un atome d'hydrogène ou un groupe méthyle, X représente un atome d'oxygène ou un groupe de formule NR', R' représentant un atome d'hydrogène ou un groupe comportant 1 à 6 atomes de carbone, R2 représente un groupe alkylène comportant 1 à 22 atomes de carbone, Y représente un atome d'oxygène, un atome de soufre ou un groupe de formule NR", R" représentant un atome d'hydrogène ou un groupe comportant 1 à 6 atomes de carbone, et R3 représente un groupe insaturé comportant 8 atomes de carbone et au moins deux liaisons doubles. L'invention concerne en outre un procédé de préparation de monomères de ce type, des polymères pouvant être obtenus à partir d'un mélange de monomères de ce type, ainsi que des produits de revêtement contenant lesdits polymères.
