Abstract
An interlayer for laminated glasses, includes two outer layers of a material selected from poly(vinyl butydownral) (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.
