Abstract
An emulsion interpolymer polymer composition suitable as a binder resin for fibrous substrates such as woven or nonwoven products including textiles, apparel in general, papers, scrim, engineered fabrics, glass or other mineral fibers, roofing or flooring materials, comprises a copolymer obtainable by reacting: a) 3-97 pphwm of vinyl acetate; b) 97-3 pphwm of at least one vinyl ester of an aromatic carboxylic acid; and c) 10-0.1 pphwm of at least one functional monomer and optionally further comonomers.

- and
- c) 10-0.1 pphwm of at least one functional monomer;
- and optionally
- d) 50-1 pphwm of at least one vinyl ester of α-monosubstituted fatty acids;
- and/or
- e) 35-5 pphwm of at least one α-olefin;
- and/or
- f) 45-5 pphwm of at least one vinyl ester of neoalkanoic acid;
- and/or
- g) other comonomers.
