摘要： 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).

摘要： The preparation of polyvinylbutyral is commonly effected by the acetalization of polyvinyl alcohol with n-butyraldehyde, either in an organic solvent or in water. By varying the reaction conditions it is possible to obtain the polyvinylbutyral in a coarse-grain or fine-grained form. The production of polyvinylbutyral having improved properties is possible by using a polyvinylbutyral having a content of from 17 to 24% by weight of vinyl alcohol units as starting material for an after-treatment in the presence of an organic sulfonic acid having an emulsifying effect. The polyvinylbutyral obtained is particularly suitable for the manufacture of compound sheets.

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.
