摘要

HOE 78/F 231 TRANSPARENT POLYVINYL BUTYRAL SHEET AND PROCESS FOR THE MANUFACTURE THEREOF of the disclosure: The tendency to blocking of polymer sheets can be reduced by means of anti-blocking agents. Suitable anti-blocking agents in transparent polyvinyl butyral sheets are especially montanic acid esters, which do not adversely affect the adhesion of the sheet to glass. The polyvinyl butyral sheets are used as interlayers of laminated glass (safety glass).
