Articles having improved clarity, prepared from propylene-ethylene copolymers

Molded articles are prepared from propylene-ethylene copolymers and exhibiting improved clarity and strength properties. Articles prepared include bottles and other thin-walled articles. The articles are prepared using an isotactic propylene-ethylene random copolymer resin having an ethylene content of from about 0.5 to about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 1.5 percent. The injection molded article may exhibit less than about 20 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm). Articles may also be prepared from similar copolymers having an ethylene content greater than about 3 percent by total weight of copolymer, with a xylene solubles content of less than about 4 percent by total weight of copolymer. These articles may exhibit less than about 13 percent haze, as determined by ASTM D1003, at a thickness of about 0.08 inch (2.03 mm).
