Abstract:
An epoxy bulk resin composition consisting of(A) a compound which contains at least two 1,2-epoxide groups and which is the reaction product of a reaction mixture consisting of(A1) one or more compounds containing at least two 1,2-epoxide groups, optionally in admixture with one or more monoepoxides, and(A2) one or more amines selected from(A21) amines of the formula I ##STR9##whereR.sup.1 is an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical, each of which may be branched or unbranched, each having from 1 to 30 carbon atoms, each which may be unsubstituted or substituted by one or more of hydroxy, alkoxy, or halogen groups,R.sup.2 and R.sup.3 are each, independently of one another, hydrogen or one of the radicals specified under R.sup.1, with the proviso that in the case of R.sup.2 and R.sup.3 being hydrogen, the remaining radical R.sup.1 is one of the following substituents ##STR10##where the radicalsR.sup.4 to R.sup.9 are each, independently of one another, an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon radical, each of which may be branched or unbranched, each having from 1 to 30 carbon atoms, each of which may be unsubstituted or substituted by one or more of hydroxy, alkoxy, or halogen groups, and R.sup.1 and R.sup.2 can form a cycloaliphatic ring having up to 8 carbon atoms, which may be unsubstituted or substituted with one or more of lower alkyl, lower alkoxy, halogen, or dialkyl amino groups, where R.sub.3 is then a hydrogen atom, or(A22) amines of the formula II ##STR11##R.sup.11 and R.sup.12 are each, independently of one another, hydrogen, a saturated or unsaturated straight-chain, branched or cyclic, with or without heteroatoms in the ring, alkyl having up to 15 carbon atoms, or R.sup.11 and R.sup.12 together can form a cyclic alkylene radical having up to 8 carbon atoms, which is unsubstituted or monosubstituted, disubstituted or trisubstituted by alkyl groups having from 1 to 3 carbon atoms,R.sup.13 is hydrogen or methyl,x is an integer from 1 to 100, andf is 2 or 3,wherein theR.sup.11, R.sup.12, and R.sup.13 groups can vary in the repeating units; or(A23) diprimary diamines of the formula III ##STR12##whereR.sup.14 to R.sup.17 are independently hydrogen or an alkyl group having from 1 to 8 carbon atoms, andR.sup.18 is a direct bond, a linear, branched or cyclic, alkylene group, which may be unsubstituted or substituted with one or more of lower alkyl, lower alkoxy, halogen, or dialkyl amino groups, or an arylene or heteroarylene group, orR.sup.14 together with R.sup.16 or R.sup.18 and the atoms connecting them can form a cycloaliphatic, aromatic, or heteroaromatic ringwith the proviso that at least one of the radicals R.sup.14 to R.sup.17 is an alkyl group if R.sup.18 is a direct bond or a linear alkylene group;the amounts of substances (A1) and (A2) being chosen in such ratio that at least two epoxide groups per molecule of (A) are retained,(B) optionally one or more 1,2-epoxide compounds which is different from that of (A1) or is the unreacted proportions of the compounds (A1) from the preparation of the compounds (A),(C) one or more hardeners.
