Patent

CA 2265844

Propenyl ether compounds of the following general formula (1) CH3-CH=CH-(OR1)n- OCO-X-COO-(R2O)n-CH=CH-CH, and allyl ether compounds of the following general formula (2) CH2 CH-CH2-(OR6)n-OCO-X- COO-(R7O)n-CH2-CH=CH2, both curable by free--radical polymerization, wherein X is -CH=CH- or -CH2-C(=CH2)-; R1, R2, R6 and R7 are each alkylene having 2 to 4 carbon atoms or cycloalkylene having 5 to 12 carbon atoms; and n is 1 to 5, with the proviso that when n is 1 in the formula (2), R6 and R7 are each alkylene having 3 to 4 carbon atoms or cycloalkylene having 5 to 12 carbon atoms. These compounds are obtained by the reaction of a corresponding dicarboxylic acid or a derivative thereof with an alcohol. The compounds of the general formula (1) are obtained by isomerizing allyl ether compounds.

La présente invention concerne des composés de propényléther représentés par la formule générale (1) suivante CH3-CH=CH-(OR<1>)n-OCO-X-COO-(R<2>O)n-CH=CH-CH3 et des composés d'allyléther représentés par la formule générale (2) suivante CH2-CH=CH2-(OR<6>)n-OCO-X-COO-(R<7>O)n-CH2-CH=CH2. En l'occurrence, X est -CH=CH- ou -CH2-C(=CH2)-; R<1>, R<2>, R<6> et R<7> sont chacun C2-C6 alkylène ou C5-C12 cycloalkylène; 'n' vaut 1 à 5, mais lorsque n=1 dans la formule générale (2), R<6> et R<7> sont chacun C3-C4 alkylène ou C5-C12 cycloalkylène. Ces composés sont obtenus par réaction d'un acide dicarboxylique correspondant, ou de l'un de ses dérivés, avec un alcool. Les composés représentés par la formule générale (1) sont obtenus par isomérisation de composés d'allyléther.
