INTERLAYER HAVING IMPROVED LAMINATION PROCESSABILITY

Interlayers having improved lamination processability while also having excellent sound or acoustic properties are disclosed. The interlayers have a warm shrinkage of less than about 4%, a static coefficient of friction (COF) of less than 1.50 when measured according to ASTM D1894 with an interlayer to interlayer configuration, and wherein the laminated glazing has a damping loss factor (η) of at least 0.20 when measured at 20° C. according to ISO 16940.
