Polyvinyl acetals capable of forming emulsifier-free aqueous dispersions and redispersible dry powders, process for their manufacture and use |
| abstract |
Production of polyvinyl acetals which can form emulsifier-free and surfactant-free aqueous dispersions and redispersible dry powders and contain copolymeric polyvinyl acetals with sufficient proportions of sulfo salt-bearing comonomer units which are derived from copolymeric polyvinyl alcohols (PVAL-enes) which contain sulfonate group-containing salt comonomer units in the salt formers contained. The preparation is carried out by acetalization of the starting polyvinyl alcohols to be used with aldehydes or aldehyde acetals under acid-catalyzed acetalization conditions in an aqueous medium, emulsifier-free stable aqueous polyvinyl acetal dispersions being obtained, from which dry redispersible polyvinyl acetal powders can be obtained by spray drying or freeze drying. The polyvinyl acetals according to the invention can be plasticized both in their aqueous dispersion form and in the dry powder form by mixing in plasticizers. The polyvinyl acetals according to the invention can be used both in the aqueous dispersion form and in the dry powder form in numerous fields of application in which polyvinyl acetals of a previously known type are usually already used. In addition, due to the advantageous property spectrum of polyvinyl acetals according to the invention, numerous new areas of application are accessible. |
