Abstract: A process for the preparation of a redispersable, free-flowing dispersion powder of a vinylpyrrolidone-vinyl acetate copolymer containing from 15 to 40% by weight of copolymerised vinylpyrrolidone, in which the mixture of monomers is copolymerised in organic solution, the resultant solution is subjected to solvent exchange with water after addition of a surfactant, and the resultant dispersion is spray-dried or freeze-dried, the dispersion powder as such, and the use thereof for the preparation of coating compositions, glues and adhesives and in particular of the matrix and/or coating of solid pharmaceutical depot forms and of hair-spray formulations.
