A thermoplastic sheet that includes a continuous phase and a dispersed phase, where A) the continuous phase contains a polymer composition resulting from the polymerization of a monomer mixture containing a styrenic monomer and an alkyl (meth)acrylate monomer in the presence of the dispersed phase; and B) the dispersed phase contains one or more block copolymer selected from diblock and triblock copolymers of styrene-butadiene, styrene-butadiene-styrene, styrene-isoprene, styrene-isoprene-styrene, partially hydrogenated styrene-isoprene-styrene. The thermoplastic sheet is formed by extruding a thermoplastic composition that is cut to desired dimensions to form thermoplastic items, e.g. identification cards, credit cards, bank cards, key cards, gift cards, phone cards, playing cards, menus, and the like. Indicia and/or printing can be applied to the items to provide for commercial applications. The sheet may be opaque or may be relatively clear to transparent with a Haze value of 0.01% up to 10%.
