    Abstract: A polymer interlayer with improved acoustic properties. The polymer interlayer comprises a first polymer layer, a second polymer layer, and a third polymer layer. The first polymer layer is positioned between the second polymer layer and the third polymer layer. The first polymer layer is formed from a resin comprising polyvinyl acetate (PVAc). The first polymer layer has a Tg of less than about 20° C. and a peak tan δ greater than about 2.0.

    Abstract: A polymer interlayer that resists formation of optical defects. The polymer interlayer comprises a first polymer layer, a second polymer layer, and a third polymer layer. The first polymer layer is positioned between the second polymer layer and the third polymer layer. The first polymer layer has a glass transition temperature of less than about 20° C. and the second and third polymer layers each have a glass transition temperature of more than about 25° C. The polymer interlayer has an edge. The first polymer layer is not present within a portion of the polymer interlayer. The portion of the polymer interlayer extends a distance X from the edge of the polymer interlayer, with the distance X being between 0.2 and 40 cm.
