ABSTRACT:
The present invention is concerned with new and improved binders for the production of foamed or cellular articles which have a high degree of absorbency, and retain their bonded character as well as absorbency through numerous wash-dry cycles. The cellular articles are bonded by a novel self-cross-linking binder comprising a copolymer of (a) N-methylol-amine or -amide units, (b) sulfonic acid units which contain no basic nitrogen atoms or group, and (c) certain acrylic units of neutral but mildly hydrophilic character which contain no basic nitrogen atoms or group.
