REDUCTION OF THE ADHESION TO GLASS OF THERMOPLASTIC PLASTICIZERS CONTAINING POLYVINYLBUTYRAL MOULDING COMPOSITIONS

摘要

Reduction in the adhesion to glass of thermoplastic, plasticized polyvinylbutyral molding compositions, in particular sheeting, by the addition of a metal salt and/or metal chelate of an enolizable beta -diketone, 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. It is preferable to employ the non-stick agent 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 a laminating layer for the production of glass laminates.
