The present invention relates to 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives of formula (I) as such, to a process for preparing the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives, to the use of the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives as hardeners for epoxy resins, as an intermediate in the preparation of triisocyanates, as initiators for polyetherols and/or as monomers for the preparation of polyamides, to triisocyanates derived from the 2-N,N-(bis-2-aminoalkyl)-1,2-alkyldiamine derivatives of formula (I) and also to a process for preparing these triisocyanates.
Abstract:
Cured epoxy resins are widespread because of their excellent mechanical and chemical properties. Typically, epoxy resins based on bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers are used, but these are problematic for many sectors because of their effect on the endocrine system. The present invention relates to glycidyl ethers of divinylbenzene-based diols and/or polyols, and to curable epoxy resin compositions based thereon as alternatives to the bisphenol A diglycidyl ethers or bisphenol F diglycidyl ethers, or the epoxy resin compositions based thereon.
