Abstract

Reduction in the adhesion to glass of thermoplastic, plasticized polyvinylbutyral molding compositions, in particular sheeting, by adding the magnesium salt of sulfonic acids or sulfuric acid half-esters or mixtures of these compounds as an non-stick agent, preferably in amounts of 0.003 to 0.3% by weight, relative to the plasticized polyvinylbutyral. The non-stick agent is preferably employed in the form of a solution in the plasticizer. The use of the sheeting having an adhesion to glass reduced in accordance with the invention as the laminating layer for the production of glass laminates.
