| 摘要 |
The invention comprises polyamino derivatives of polyhalogenated polyphenyl benzenes of the general formula <FORM:1086781/C2/1> in which R1Z and R2Z each represents an atom of hydrogen or a group formed by a radical R1 or R2 which may be aliphatic, aromatic or heterocyclic and by a terminal group Z which is -OH, -NH2, =NH, -COOH, -CH3 or Cl, m is 2 or 3, a is 3 or 4, b is at least 2 and is equal to or less than 6 - (n + m) and n is 0 or 1. They may be prepared by reacting a compound of formula <FORM:1086781/C2/2> with a polyhalogenated polyphenyl benzene, the reaction being carried out at 70-300 DEG C. in a medium consisting of the cumino compound or the amino compound dissolved in water or another inert solvent. Examples are given of the reaction (a) between mono-ethanolamine and various chlorinated terphenyls and chlorinated triphenyl benzenes and (b) between ethylene diamine and chlorinated terphenyls. The products may be used as hardeners for polyepoxy resins and for the production of polyesters. |
