  • Patent number: 7740951
    Abstract: Multilayered structures formed from two or more polymeric layers are fabricated to obtain a single structure preferably having advantages of each of the separate layers. Polyolefin-based substrates can provide a layer with a good balance of stiffness and impact resistance, excellent processability, and relatively lower cost. Tie layers, preferably physically positioned adjacent a polyolefin-based substrate layer, facilitates adhering additional layer(s) together with the polyolefin-based substrate. Suitable tie layers generally include a multicomponent blend of at least one vinyl cyanide-containing component and at least one styrenic block copolymer component. Preferably, the additional layers include at least one acrylate-based cap layer, which can have a glossy, scratch resistance outer layer with excellent optical characteristics.
