MODIFIED POLYVINYLACETALS WITH LOW SOLUTION VISCOSITY |
摘要 |
Modified polyvinyl acetals are prepared by saponification of 1-alkylvinyl acetate-vinyl acetate copolymers, which contain 1-alkylvinyl acetate/vinyl acetate in a weight ratio of 1/99-40/60 and subsequent acetalization the saponification products containing at least 80% units of vinyl alcohol and 1-alkyl vinyl alcohol with one or more aliphatic aldehydes with 1-6 C atoms under acid catalysis in an aqueous and/or organic medium; as well as to a method for the manufacture and the use thereof, especially in printing inks. |
