    Abstract: A process for preparing glycerol carbonate methacrylate, wherein glycidyl methacrylate is reacted with carbon dioxide in the presence of a catalyst and a solvent,
    wherein the catalyst is potassium iodide, the solvent is acetonitrile, one or more monoalcohols, or any desired mixture of acetonitrile and one or more monoalcohols, and the reaction of glycidyl methacrylate with carbon dioxide is carried out at a pressure from 0.5 to 5 bar.

    Abstract: A curable composition comprises a) at least one epoxide compound E having at least two epoxide groups; b) at least one amine A having at least two amine hydrogens; and c) at least one acrylic ester U; wherein the epoxide compound E comprises at least one epoxide compound E′, the amine A comprises at least one amine A′, and the acrylic ester U comprises at least one acrylic ester U′ whose Hansen solubility parameters for the dipole forces δp and for the specific interactions δh satisfy the following conditions: ( δ p ⁡ ( U ′ ) - δ p ⁡ ( E ′ ) ) 2 + ( δ h ⁡ ( U ′ ) - δ h ⁡ ( E ′ ) ) 2 ≥ 1.5 ⁢ ⁢ and ( δ p ⁡ ( U ′ ) 2 + δ h ⁡ ( U ′ ) 2 ) - ( δ p ⁡ ( A ′ ) 2 + δ h ⁡ ( A ′ ) 2 ) ≥ 0 . A suitable choice of the Hansen solubility parameters of the constituents ensures that the acrylic ester is incorporated covalently into the curing material, preventing subsequent evaporation of the diluent.
