Preparation of carboxylated latices and compositions containing them.

摘要

A process for preparing a carboxylated latex containing an N-alkylolamide of an unsaturated carboxylic acid comprises carrying out the polymerisation reaction in two or more stages in which the majority (or all) of the N-alkylolamide monomer is supplied to the second stage. The reaction may be carried out using a batch procedure but a continuous reaction is preferred. The product latex is particularly suitable for paper and textile applications and especially for use in paper coating compositions.
