Abstract: Production of a polymer powder that is readily redispersible and cross-linkable in water comprises spray drying of an aqueous dispersion of polymer particles with addition of a hydrophilic and a hydrophobic anti-blocking agent whereby the spray drying is carried out in the presence of a hydrophobic antiblocking agent and the resulting polymer powder in homogeneously mixed with a hydrophilic antiblocking agent in a subsequent step.

Abstract: Disclosed is the use of a formaldehyde-free aqueous binder as a binder for sustainable raw materials in the form of fibres, chips or particles for making mouldings, said binder containing: A) a polymer obtained by radical polymerisation consisting to the extent of 5 to 100 wt% of an ethylenically unsaturated acid anhydride or bicarboxylic acid, the carboxylic acid groups of which can form an anhydride group, and B) an alkanol amine with at least two hydroxyl groups.
