    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.

    Abstract: The present invention relates to a process for preparing a terephthalic diester by reacting terephthalic acid with at least one alcohol, wherein terephthalic acid is suspended in the alcohol in a dispersing tank, the preliminary suspension is passed from the dispersing tank into a reactor and converted in the presence of an esterification catalyst, and water of reaction is distilled off together with the vapor as alcohol-water azeotrope, the vapor is at least partly condensed, the condensate is separated into an aqueous phase and an organic phase and the organic phase is conducted through a column in which the organic phase is run counter to at least a portion of the vapor, and the organic phase is collected in the lower region of the column and at least partly passed into the dispersing tank.
