Abstract

An aromatic aldehyde-amine condensation resin has recurring units <FORM:1080526/C3/1> or <FORM:1080526/C3/2> Ar1 is <FORM:1080526/C3/3> , <FORM:1080526/C3/4> , <FORM:1080526/C3/5> , <FORM:1080526/C3/6> , <FORM:1080526/C3/7> or <FORM:1080526/C3/8> X is O, S, CO, SO2 or C1-C3 alkylene radical; Ar2 is <FORM:1080526/C3/9> , <FORM:1080526/C3/100> , <FORM:1080526/C3/111> , <FORM:1080526/C3/122> , <FORM:1080526/C3/133> or <FORM:1080526/C3/144> Y is O, S, CO, SO2, a C1- 3 alkylene radical or <FORM:1080526/C3/155> and Ar3 is a tetravalent aromatic radical derived from Ar2 by adding a bond ortho to each of the bonds shown in the groups defined by Ar2. The radicals Ar1, Ar2 and Ar3 may contain one or two lower alkyl, lower alkoxy, halogen or amino substituents. The resins may be prepared by reacting an aromatic amine: H2N-Ar2-NH2 or (H2N)2Ar3(NH2)2 having the amino groups in ortho pairs with an aromatic dialdehyde Ar1(CHO)2; reaction may take place in an inert solvent in the substantial absence of oxygen at a temperature from 100 DEG to 250 DEG C.
