Abstract

This invention relates to an aqueous binder composition containing a) at least one polymer P and b) at least one saccharide compound S, such that an amount of the saccharide compound S is ≧10 and ≦400 parts by weight per 100 parts by weight of polymer P, wherein an amount of an additional formaldehyde-containing binder is ≦50 parts by weight per 100 parts by weight of the summed overall amounts of the polymer P and the saccharide compound S. This invention also relates to a process for producing a shaped articles from granular and/or fibrous substrates where an aqueous binder composition of the present invention is applied to the granular and/or fibrous substrate, the granular and/or fibrous substrate thus treated is optionally shaped and then the granular and/or fibrous substrate thus obtained is thermally treated. This invention also relates to shaped articles obtained by a process of the present invention.
