The present invention relates to the use of cyclic carbonates of the formula I or a mixture thereof in epoxy resin compositions and also to epoxy resin compositions which comprise such cyclic carbonates. n n n n n n n n n n in which n R 1 and R 2 independently of each other are hydrogen, C 1 -C 6 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl, C 5 -C 6 -cycloalkyl, phenyl, phenyl-C 1 -C 4 -alkyl, C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl, or R 1 and R 2 together are a C 3 -C 11 -alkylene group; n R 3 and R 4 independently of each other are hydrogen, C 1 -C 6 -alkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl, C 5 -C 6 -cycloalkyl, phenyl, phenyl-C 1 -C 4 -alkyl, C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl, or R 3 and R 4 together are a C 4 -C 6 -alkylene group; n or mixtures thereof, as additives in epoxy resin compositions. |
