  • PHOTO-CURABLE RESIN COMPOSITION FOR USE IN STEREOLITHOGRAPHY
    Publication number: 20230322998
    Abstract: Provided herein is a curable liquid stereolithography resin comprising (a) a divinylarene dioxide, such as for example a divinylbenene dioxide (DVBDO); (b) a free radically curable component, such as for example a (meth)acrylate component; (c) a cationic photoinitiator; and (d) a free radical photoinitiator. The stereolithography resin may comprise additional components, such as a cationically curable component other than a divinylarene dioxide. Preferably, the stereolithography resin has a viscosity at 25° C. of less than 400 mPa·s.

  • Process for producing epoxides from olefinic compounds
    Patent number: 7981951
    Abstract: A process for producing an epoxide such as a cycloaliphatic diepoxide by the reaction of an olefin such as a cycloaliphatic diene with hydrogen peroxide (H2O2) as an oxidant in the presence of a catalytic system under pH control for example at a pH of less than about 5. The present invention is advantageously used for the epoxidation of olefinic compounds such as olefins and aliphatic or aromatic dienes.
