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.

Abstract: Thermoplastic polyolefin blends with a good stiffness/impact balance, as well as enhanced surface durability, contain semi-crystalline polypropylene resin component, a propylene-based elastomer component, and an optional but preferred styrene-based elastomer component. The propylene-based elastomer (PBE) is characterized as having at least one of a) a plurality of identifying band positions at 998 cm?1, 974 cm?1, and 733 cm?1, as measured by Fourier Transform Infrared Spectroscopy (FTIR); or one or more glass transition temperatures (Tg) from about ?15° C. to ?35° C., as measured by Differential Scanning Calorimetry. The surface of articles made from such a thermoplastic blend shows increased scratch resistance and a decrease in stress whitening.
