NEW GRAFTED SULPHONATED POLYESTERS,A METHOD OF PREPARING THEM AND THEIR APPLICATION TO SIZING TEXTILE THREADS AND FIBRES

摘要

Grafted sulphonated polyesters consisting of a sulphonated polyester backbone carrying grafts derived from a monomer composition based on unsaturated carboxylic acid, butyl acrylate and a large quantity of monoethylenically unsaturated ester of a carboxylic acid (vinyl acetate). …??They are prepared by polymerisation of the monomer composition in the presence of a water-dispersible sulphonated polyester. …??The aqueous dispersions or the aqueous solutions of the said grafted sulphonated polyesters can be employed for sizing yarns and textile fibres. …IMAGE…
