    摘要： Polyvinylbutyral of reduced tackiness and improved tensile strength is prepared by acetalization of polyvinyl alcohol, which is capable of association, in the associated state with n-butyraldehyde in aqueous phase in the presence of an acid catalyst. In the process for its preparation from more highly saponified, associated polyvinyl alcohol having a vinyl acetate unit content of less than 1% by weight, the acetalization is started preferably at temperatures below 20.degree. C. and the temperature is raised to above 40.degree. C. in the course of the reaction. Use for the production of plasticized thermoplastic polyvinylbutyral films and use of the latter as the joining layer in laminated glass.

    摘要： Glass laminates used as safety glass consist of several sheets of glass united by adhesive interlayers. The bond strength of such interlayers may be determined in simple manner using a special test specimen by the tensile shear test. The test specimen is parallelipiped-like and the individual sheets thereof are divided each to form an obtuse fracture, the fractures facing the interlayer being staggered. The minimum force required for detaching the interlayer from the individual sheets of the glass laminate is taken as a measure for the bond strength.
