Nitrogen-containing polymers having terminal hydroxyl groups Nitrogen-containing polymers, having terminal hydroxyl groups, of the formula I (I) in which X1 and X2 independently of one another are -H or , Z is OH and Y is NH or Z and Y together are N, n is an integer from 1 to 2000, R1 is, for example, a radical of the formula VIIa (VIIa) R2 consists, for example, of 95 mol % of groups of the formula II and 5 mol % of groups of the formula III (III), (II), in which R4 is hydrogen or C1-C4alkyl, the R5s independently of one another are hydrogen, halogen or C1-C4alkyl, x is zero or an integer from 1 to 3 and y is zero or an integer from 1 to 4, and R3 is, for example, 1,4-phenylene, are suitable, for example, as matrix resins, particularly as a mixture with epoxy resins for formulating matrix resins of very high toughness.
