Claims
- 1. A curable mixture containing (a) a polyepoxide compound which contains on average more than one epoxy group in the molecule and (b) a curing agent which is a dimethylamino derivative of the formula I ##STR47## wherein X is 1,3-propylene or ethylene or alkyl-substituted ethylene, and
- R is the radical of the formulae ##STR48## OR.sup.4 (VII) or OR.sup.11 OXN(CH.sub.3).sub.2 (XI), wherein R.sup.1 is alkyl, cycloalkyl, or aryl or aralkyl which is unsubstituted or substituted by halogen or C.sub.1 -C.sub.4 alkyl, Y is a direct bond, alkylene, alkenylene, cycloalkylene or arylene, R.sup.2 is a hydrogen atom or has the meaning of R.sup.3, and R.sup.3 is alkyl, cycloalkyl, or aryl or aralkyl which is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl or halogen, R.sup.4 is alkyl, alkenyl, cycloalkyl, cycloalkylalkylene, or aryl or aralkyl which is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl or halogen, or is ##STR49## wherein R.sup.5 is a hydrogen atom or methyl and Z is CN, CH.sub.2 NH.sub.2 or CH.sub.2 N(CH.sub.3).sub.2, and R.sup.11 is alkylene, cycloalkylene or arylene, and X is additionally neopentylene if R is the radical OR.sup.4, or
- X is ethylene, 1,3-propylene or 1,3-propylene which is substituted in the 1- or 2-position by methyl, and
- R is the radical of the formulae ##STR50## wherein each or X and Y independently is as defined above, n is 0 or 1, R.sup.6 is a hydrogen atom, alkyl, cycloalkyl, .beta.-cyanoethyl or .beta.-cyanoethyl which is substituted in the 1- or -2 position by methyl, R.sup.7 is alkyl, alkenyl, cyclalkyl, aryl, aralkyl, alkaryl or alkaralkyl, each of R.sup.8 and R.sup.10 is a hydrogen atom and R.sup.9 is alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkaralkyl, 3-(dimethylamino) propyl, or each of R.sup.8 and R.sup.9 independently is C.sub.1 -C.sub.4 alkyl or phenyl and R.sup.10 is a hydrogen atom or R.sup.8 is a hydrogen atom, R.sup.9 is alkyl, cycloalkyl, aryl, aralkyl, alkaryl or aralkaryl, and R.sup.10 is .beta.-cyanoethyl or .beta.-cyanoethyl which is substituted in the 1- or 2-position by methyl.
- 2. A process for the production of a cured mixture consisting of a polyepoxide compound containing on average more than one epoxy group in the molecule and a curing agent, which process comprises heating the polyepoxide compound in the presence of a dimethylamino derivative of the formula I according to claim 1.
- 3. A process according to claim 2, wherein the mixture is heated at the most to below the decomposition temperature of the polyepoxide compound, preferably to a temperature not exceeding 150.degree. C.
