Abstract

Abstract Translated from German Die Klebneigung von Polymer-Folien kann mit Hilfe von Antiblockmitteln vermindert werden. Als Antiblockmittel in transparenten Polyvinylbutyral-Folien eignen sich insbesondere Montansäureester; dabei wird die Haftfähigkeit der Folie an Glas nicht verändert. Die Polyvinylbutyral-Folien werden als Zwischenschichten für, Verbindungsglas verwendet. The tendency of polymer films to stick can be reduced with the help of antiblocking agents. Montanic acid esters are particularly suitable as antiblocking agents in transparent polyvinyl butyral films; the adhesion of the film to glass is not changed. The polyvinyl butyral films are used as intermediate layers for connecting glass.
