A new range of epoxides having at least one primary epoxide group is provided. The epoxides are obtained from esterification products having at least one primary alkenyl group, which esterification products are yielded when an alcohol is esterified, at a molar ratio hydroxyl to carboxyl groups of 1:0.8 to 1:5, with at least one linear or branched alkenoic acid having one carboxyl group and one primary alkenyl group. The alkenyl group or groups in said esterification products is/are, after an optional removal of excess or otherwise unreacted carboxylic acid, oxidized in the presence of an effective amount of at least one oxidizing agent to yield corresponding number of primary epoxide groups. In a further aspect, a process for production of said epoxides is provided and in yet a further aspect a curable composition comprising at least one epoxide as provided by the present invention. |
