    Abstract: 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).

    Abstract: A process including vis-breaking of polypropylene in the presence of 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane to obtain vis-broken polypropylene is provided. The vis-broken polypropylene may be pelletized to obtain pellets. A ratio of a melt flow rate (MI2) of the pellets to a melt flow rate (MI2) of the polypropylene prior to the vis-breaking may be greater than 1:1 and at most 4:1. The pellets may be used to form articles.

    Abstract: A polymer composition may include polyolefin having a molecular weight distribution of greater than or equal to 8 as measured by GPC and a metallic acrylate salt. The polymer composition may be characterized by one or more of: a melt flow rate of from 0.1 g/10 min to 10 g/10 min; a melt flow viscosity between 2,000 Pa·s and 6,000 Pa·s; a die swell of between 2 and 8; and a die swell characteristic time of between 0.3 seconds and 1.2 seconds. The polymer composition may be in the form of foam. A process of forming foam may include supplying polymer composition including metallic acrylate salt and polyolefin resin, and mixing the polymer composition with foaming agent. A foam may include a polymer composition that includes polyolefin and polar polymer and does not include an ionomer. The foam may have a foam density of less than 0.25 g/cc.
