摘要
Plasticizer containing polyvinylbutyral sheets are known intermediate layers for glass laminates. Generally, the polyvinylbutyral used for this application contains certain amounts of vinyl alcohol units and vinyl acetate units. In order to adjust an optimum adhesion to glass, certain additives are mixed with the polyvinylbutyral, which additives must not cause discoloration of the laminate and deterioration of the transparency. Betains are especially suitable anti-adhesives, and efficient in very small amounts.
