摘要

Solvent free epoxy resin mixture containing components made of renewable resources (at least 70 wt.%), comprises (in wt.%) at least one multifunctional glycidyl compound made of renewable resources (20-90) as a cross-linking component, at least one multi-functional aromatic monomer with phenolic hydroxyl groups and their multifunctional oligomers and/or polymers (10-80) as a crosslinking agent, and/or an activator for crosslinking. Independent claims are also included for: (1) preparing the epoxy resin mixture, comprising dissolving the multi-functional glycidyl compound, multi-functional aromatic monomer with phenolic hydroxide groups and its oligomers and/or polymers, and the activator, in an organic solvent or in the dissolved oligomers, and then removing the solvent by vacuum; and (2) use of the epoxy resin mixture, for preparing curable molding compositions, textile tiles or prepregs by curing the epoxy resin mixture.
