Abstract
The invention relates to a multi-layer acrylic composition having at least two impact modified layers. The outer layer is an acrylic layer containing impact modifiers having a particle size of less than 225 nm, and the impact modifiers in the inner thermoplastic layer have a particle size of greater than or equal to 225 nm. The invention also relates to multi-layer composites having the multi-layer acrylic composition on one or both sides. The multi-layer acrylic composition can also include blends of acrylic and fluoropolymers.
