Abstract
A thermoplastic polymer film comprising a multilayer film having an interpenetrating polymer network (IPN) layer and a polymer layer is provided. The multilayer thermoplastic polymer film may possess beneficial and desirable properties useful in protecting surfaces from harmful environmental conditions or elements, such as for example, stain and scratch resistance as well as high gloss. Methods of making the multilayer film with interpenetrating polymer network are also provided.
