摘要： A process for preparing recyclable fiber composites, comprising bonding fibers with a polymeric bonding agent applied as an aqueous polymer dispersion to said fibers, the polymeric bonding agent comprising at least one addition polymer which, in the state of an aqueous dispersion, has a film forming capability at the temperature at which the addition polymer is combined with said fibers, and said aqueous polymer dispersion, when subjected to a change in pH, is converted into an aqueous solution of the addition polymer. The aqueous addition polymer of the addition polymer dispersion can contain protic acid groups, and the state of the dispersion can be converted to an aqueous addition polymer solution by raising the pH of the aqueous medium. Alternatively, the addition polymer may contain basic groups, in particular, amino groups, and its state as a dispersion can be converted into an aqueous addition polymer resolution by lowering the pH of the aqueous medium.
