PLASTICIZERS CONTAINING POLYVINYLBUTYRAL MOULDING COMPOSITIONS HAVING A REDUCED ADHESION TO GLASS

摘要

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.
