Abstract
A process for preparing a polymer comprising reacting at least the components i) to iii) in any order: i) a compound of the Formula (1): Formula (1) wherein: T1 and T2 independently are HO—, HS— or R1HN—; Q1 and Q2 independently are —NR2—; A1 and A2 independently are an optionally substituted divalent organic linking group; R1 when present is H or an optionally substituted alkyl, aryl or heterocyclyl group; R2 is H or an optionally substituted alkyl, aryl or heterocyclyl group; Z is an HO— group or a group of the Formula (2) or (3); Formula (2) wherein: L is —HN—, —O— or —S—; X is an optionally substituted organic group; Formula (3) wherein: each X independently is an optionally substituted organic group; in both Formulae (2) and (3) the asterisk (*) signifies the point of attachment to the triazine ring: ii) a diisocyanate; iii) an isocyanate reactive compound having at least one ionic group.
