Abstract (en)
[origin: WO2022184619A1] What is described is a polymerizable composition for producing a polyacrylamide hydrogel, a corresponding polyacrylamide hydrogel, and fire-retardant glazing comprising an aforementioned polymerizable composition or an aforementioned polyacrylamide hydrogel. Also described is a process for producing fire-retardant glazing as well as the use of an aforementioned polymerizable composition and/or an aforementioned polyacrylamide hydrogel, in each case as fire retardant for fire-retardant glazing and/or in the production of fire-retardant glazing. Also disclosed is the use of one or more polyhydroxy compounds, in particular glycerol, for improving adhesion of a polyacrylamide hydrogel to fire-retardant glazing.
