Plasticizer-containing polyvinylbutyrals with improved adhesion-reducing properties with respect to silicate glass, processes for their preparation and their use

摘要: Preparation of plasticizer-containing polyvinylbutyrals (PVB) which are suitable for the production elastic interleaving films with improved adhesion-reducing properties laminated glass panes siliceous glass. They comprise, as additives, active amounts salts metals groups Ia, IIa, IIb and IIIa periodic table elements naturally occurring resin acids or derivatives acids, and, if appropriate, customary stabilizers auxiliaries. prepared by mixing components plasticizing component mixtures. can be shaped thermo-plastically methods plasticized PVB have advantageously respect to used panes.
