ABSTRACT:
A polyvinylbutyral-based thermoplastic composition which is useful for forming thermoadhesive films for adhering bases onto a glazing. The composition comprises a polyvinylbutyral resin with a hydroxyl group content of between 22 and 26% by weight, a plasticizer for the resin and an orthosubstituted phenolic antioxidizing agent. This composition is useful for forming a thermoadhesive film having good adhesion at the surface of the glass and good stability at high temperatures.
