The object of investigation was thin (< 200 m) films, formed by casting from water based mixtures of polyvinyl alcohol (PVA) water solution and polyvinyl acetate (PVAc) water suspension. So starting systems essentially was suspensions of plasticized PVAc particles (1- 5 m in diameter) in PVA water solution. Systems with full range of PVAc volume fraction PVAc were studied. Kinetic relationships of several parameters which characterize film formation in drying process (water removing, decrease of volume and thickness of drying layer, viscosity growth of PVA solution, reducing of distance between PVAc particles etc.) were compared and scrutinized.
