Abstract
Vinyl ester emulsion copolymers are modified to introduce improved thermosetting cure capacity by including in the copolymer a proportion of a formaldehyde addition product with an allyl carbamate. These emulsions are useful as binders for fibers in non-woven fabrics where the improved cure confers superior resistance to home laundering in aqueous detergent solutions.
