摘要： The invention relates to aliphatic amines, methods for preparing the same and use thereof, particularly their use in curing agents. The method for preparing an aliphatic amine comprises reacting a reaction composition comprising an amino acid and an amine compound capable of dissolving the amino acid to obtain the aliphatic amine, wherein the content ratio of the amino acid to the amine compound is 1:10000-1:1, preferably 1:100-1:2, most preferably 1:10-1:2. The method for preparing an aliphatic amine provided by the present invention has a high reaction rate, a high conversion rate of the amino acid, a high purity of the aliphatic product, a long catalyst life, and easy purification of the reaction product.

摘要： The invention relates to a method for producing an object from a precursor, comprising the steps: I) depositing a radically cross-linked resin on a carrier so that a layer of a construction material connected to the carrier is obtained, said layer corresponding to a first selected cross-section of the precursor; II) depositing a radically cross-linked resin on a previously applied layer of the construction material so that an additional layer of the construction material is obtained, which corresponds to a further selected cross-section of the precursor and which is connected to the previously applied layer; III) repeating step II) until the precursor is formed, wherein, at least in step II), the deposition of a radically cross-linked resin is carried out by allowing energy to act on a selected region of a radically cross-linkable resin, corresponding to the respectively selected cross-section of the object, wherein the radically cross-linkable resin has a viscosity (23° C., DIN EN ISO 2884-1) of =5 mPas to =100000 mPas. The radically cross-linkable resin comprises a curable component, in which NCO groups which are blocked with a blocking agent, compounds having at least two Zerewitinoff-active H atoms and olefinic C═C double bonds are present, wherein the blocking agent is an isocyanate or the blocking agent is selected in such a manner that, after deblocking of the NCO group, no release of the blocking agent as a free molecule or as a part of other molecules or molecule parts occurs. Following step III), step IV) is carried out: IV) treating the precursor obtained according to step III) under conditions which are sufficient to at least partially deblock NCO groups which are present in the radically cross-linked resin of the obtained precursor, and to react the resulting functional groups with compounds having at least two Zerewitinoff-active H atoms, with the result that the object is obtained.
