Abstract
A process for preparing a polymer comprising reacting at least the components i), ii) and optionally iii) to form a pre-polymer: i) a compound of the Formula (1); wherein: T1 and T2 are each independently HO—, HS— or HNR1—; Q1 and Q2 independently are —NR2—; A1 and A2 independently are an optionally substituted divalent organic linking group; Z is a halogen; 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; ii) a diisocyanate; iii) optionally an isocyanate reactive compound; and then reacting the pre-polymer with at least component iv): iv) one or more compounds selected from an organic amine, alcohol or thiol provided that at least one of the organic compounds in component iv) has at least one ionic group.
