Plasticizer-containing polyvinylbutyrals, method for producing the same and the use thereof, especially for producing films for use in laminated safety glasses

摘要

The invention relates to plasticizer-containing polyvinylbutyrals that are characterized by containing as the plasticizer at least one dibenzoate of alkylene and polyalkylene glycols. The invention further relates to a method for producing said compounds, and to their use in molding compounds of all types, especially for producing films that can for example be used as an intermediate layer in laminated safety glasses.
