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.
A multilayered polymeric structure comprising:
A method of forming a multilayered polymeric structure which comprises:
A tie layer composition comprising at least one vinyl cyanide-containing component and at least one styrenic block copolymer component each present in an amount sufficient to permanently adhere at least two polymeric layers to each other when the adhesive composition is disposed therebetween.
