Abstract
The invention relates to a composite consisting of an impact-modified acrylic capstock or film on a thermoplastic olefin (TPO). A tie-layer containing a functionalized olefin-acrylic is used to improve the adhesion of the acrylic layer to the TPO and to improve the overall melt processing of the three-layer composite.
