Title:
THERMOPLASTIC MOLDING COMPOSITION COMPRISING PLASTICIZER-CONTAINING POLYVINYLBUTYRAL AND USE
Document Type and Number:
Japanese Patent JPS59145235
Kind Code:
A
Abstract:
Thermoplastic molding compositions comprising 65-80% by weight (based on the molding composition) of a polyvinylbutyral which preferably contains 19-28% by weight (based on the polyvinylbutyral) of vinyl alcohol units, and 35-20% by weight (based on the molding composition) of a plasticizer mixture of 50-99% by weight (based on the plasticizer mixture) of a di-, tri- or tetra-glycol diester and 50-1% by weight (based on the plasticizer mixture) of a phosphoric acid triester. The preparation of the molding compositions by mixing the constituent components and their use for the production of shaped thermoplastic articles, in particular high-strength films for use as the bonding intermediate layer in the production of laminated glass.
