Zusammenfassung:(Cyclo)aliphatic polyamines (I), which contain urea gps. and more than 2 amino gps. and have low viscosity, are obtd. by reacting diamines of formula (II) with polyisocyanate (III) contg. isocyanurate and/or biuret gps., comprising 100-20 wt.% (IIIA) and 0.80 wt.% (IIIB) of the given formulae, using 1-5 mole (II)/NCO gp.: R -NH-A-NH-R (II); OCN-(B)-(X)n-NCO (IIIA); OCN-(B)-NCO (IIIB); R , R = H or -CH(CO2R )-CH2-CO2R ; R = 1-12C (cyclo)aliphatic hydrocarbyl; B = -(CH2)6-, -CH2-CH(Me)-(CH2)3-, -CH2CH(Me)CH2-C(Me)2-CH2-CH2 or a gp. of the formulae (IV), (V) where (X)n = a gp. of the formulae (VI) and (VII) (where n = 1-4). Also claimed are (I) obtd. by reacting diamines (II; R , R = H) and (IIIA) and (IIIB) as above and then with 1 mole maleic or fumaric ester per NH2 equiv.. Pref. (I) contain 0.01-5 pts. wt. inert cpds., esp. plasticiser.
