AZETIDINIUM-FUNCTIONALISED POLYMERS AND COMPOSITIONS CONTAINING THE SAME |
摘要 |
The invention provides a biodegradable azetidinium-functional polyester. This is useful for treating a substrate such as a cellulosic or keratinaceous textile material, preferably in the presence of a carrier. The polymer can be prepared by:a) reacting an amine-containing (di)acid or (di)ol with a suitable co-reactant, and,b) treating the product of step (a) with an epihalohydrin.Preferably step (a) occurs in the presence of a catalyst selected from the group comprising sulphuric acid, p-toluenesulphonic acid and a hafnium(IV) compound. The preferred diacid are iminodiacarboxylic acids in which each carboxylic acid moiety has a carbon number of 2-4. The preferred diols are polyalkylene glycols in which the repeat unit has a carbon number of 2-3.
