Abstract: An interlayer for laminated glasses, includes two outer layers of a material selected from poly(vinyl butyral) (PVB) and poly(ethylene-vinyl acetate) (EVA), assembled by an adhesive nanocomposite layer including a first, discontinuous phase consisting of polymeric nanodomains having a glass transition temperature (Tg) of between −50° C. and −30° C., and a second, continuous polymeric phase, referred to as the matrix, having a glass transition temperature (Tg) lower than that of the first phase, the first phase being dispersed in the second phase.

Abstract: A viscoelastic plastic interlayer intended to be arranged between two glass sheets of a glazing in order to provide it with vibroacoustic damping properties, includes two outer layers of thermoplastic adhesive, an inner layer arranged between the two outer layers, the inner layer having a loss factor tan δ greater than or equal to 1.6 at 20° C. and for a frequency range of between 2 kHz and 8 kHz, and first and second barrier layers arranged respectively between the outer layers and the inner layer 3, and composed of a viscoelastic plastic material.
