摘要： This invention relates to a glass laminate containing an interlayer based on a specified ethylene vinyl acetate-based resin composition, which is particularly suitable for higher temperature applications where polymer creep can be an issue, such as overhead architectural glazing, spandrels and bolted laminate applications, and particularly for locations where the glazing temperature can exceed 50° C., and even 60° C., for an extended period.

摘要： Polyvinyl acetal films with less blocking tendency and which allow for escape of gas during laminating to form laminated composities are prepared by a process for embossing a film comprising plasticized polyvinyl acetal with a roughness Rz on at least one surfaces of 20 to 100 μm by the steps of a. extruding of plasticised polyvinyl acetal to a film with a stochastic roughness of the surfaces of Rz =1 to 70 μm, b. embossing at least one surface of the film obtained in step a) with channels having a depth of 5-50 μm, a width of 10-200 μm and a pitch of 50-2500 μm, wherein c. the surface roughness of the elevations between the channels is at most 20% lower as obtained in step a).

摘要： A multilayer laminating film contains at least one first and one second layer of plasticized polyvinyl acetal, wherein the first layer comprises a first plasticizer and a first polyvinyl acetal with a degree of acetalization of 75.1-84.0 mol % and a molar ratio of continuous sequences of vinyl alcohol groups with 5 members with a stereochemical sequence of rrrr of more than 0.23 based on the total amount of continuous syndiotactic sequences of vinyl alcohol groups with 3 members in the polyvinyl acetal, and the second layer comprises a second plasticizer and a second polyvinyl acetal with a degree of acetalization of 60-84 mol %.

摘要： Plasiticized polyvinylacetal films with grater film-to-film uniformity are produced by a process of extruding a melt stream containing a polyvinyl acetal and a plasticizer at 150-250° C., the film having a predefined melt viscosity at 60-170° C., by providing a first melt stream of at least a first plasticizer and a first polyvinyl acetal resin and measuring its melt viscosity at 60-170° C. online; and adjusting the 60-170° C. melt viscosity by adding a second plasticizer and/or a second polyvinyl acetal resin to the first melt stream in an amount to provide a second melt stream with a melt viscosity at 60-170° C. having a difference of at most 20% to the predefined melt viscosity at 60-170° C.
