Abstract: Propylene-ethylene copolymer compositions and production methods are provided. The copolymer compositions can be particularly advantageous for use in hot fill packaging of foodstuffs. The propylene-ethylene copolymers can be produced using a Ziegler-Natta catalyst and an alkoxysilane electron donor. The compositions can have propylene as a primary monomer with an ethylene content ranging from 2.0 to 6.0 percent by weight with a xylene soluble content of less than 7.0 percent by weight.

Abstract: Polypropylene polymer compositions are disclosed that can be used to produce different types of molded articles, such as extruded piping structures. The polypropylene polymer composition contains a polypropylene random copolymer in combination with a property enhancing agent. The property enhancing agent is incorporated into the polymer composition so that the composition has relatively high impact resistance properties in combination with a relatively high flexural modulus.

Abstract: Articles having a Shore A hardness of 50 to 95 and made from polyolefin compositions comprising an ethylene-alpha-olefin interpolymer (random or block or a mixture of the two) are paintable without the need for a primer or other surface treatment with paints free of phthalate-based plasticizer and designed to paint SBS- or SEBS-type rubber based compositions. These polyolefin compositions are free of (1) phthalate-based plasticizer, (2) halogen-containing polymer, and (3) leachable, small polymeric units derived from styrene monomer. In addition, the content of the alpha-olefin in the polyolefin composition is at least 9.7 mole percent.
