ABSTRACT:
Compounds of the general formulae (I) and (II): where R1, R2and R3each independently of one another are H; C1-17alkyl; C3-12cycloalkyl, optionally substituted by C1-4alkyl groups; C4-20cycloalkyl-alkyl, optionally substituted by C1-4alkyl groups; C6-10, aryl, optionally substituted by 1-3 C1-4alkyl groups, —CN, Hal, OH, or C1-10alkoxy; C7-15phenylalkyl, optionally substituted by 1-3 C1-4alkyl groups; C3-12alkenyl; C3-12alkynyl; or aromatic or aliphatic C3-12acyl; R4, R5, R6, R7, R8, and R9each independently of one another are H; C1-17alkyl, C3-12cycloalkyl, optionally substituted by C1-4alkyl groups; C4-20cycloalkyl-alkyl, optionally substituted by C1-4alkyl groups; C6-10aryl, optionally substituted by 1-3 C1-4alkyl groups; C7-15phenylalkyl, optionally substituted by 1-3 C1-4alkyl groups; C3-17alkenyl; C3-12alkynyl; C1-12alkoxy; or OH; for formula (1) R is C1-12alkyl; C3-12cycloalkyl, optionally substituted by C1-4alkyl groups; C4-20cycloalkyl-alkyl; optionally substituted by C1-4alkyl groups; C6-10aryl, optionally substituted by 1-3 C1-4alkyl groups; C7-15phenylalkyl, optionally substituted by 1-3 C1-4alkyl groups; C3-12alkenyl; or C3-12alkynyl; and for formula (II) n=2-12; as accelerators in curable epoxy resin compositions which are used as a compression moulding compound, sinter powder, encapsulating system, or casting resin, or for producing prepregs and laminates having very good interlaminar shear strength values using the resin infusion method, wet layup method and injection methods, for producing components, especially components of large surface area.
