Abstract: Disclosed is a polymeric composition containing at least 98 wt. % of a random ethylene polypropylene copolymer and 0.01 wt. % to 1.0 wt. % of an acid neutralizer. The random ethylene polypropylene copolymer includes 4 wt. % to 12 wt. % of ethylene units and 88 wt. % to 96 wt. % of propylene units based on the total weight of the copolymer. The polymeric composition has a haze value of less than 40% as measured in accordance with ASTM D-1003 and a notched Izod impact strength of greater than 3 ft-lb/in as measured in accordance with ASTM D-256. The polymeric composition can further comprise a clarifier. Methods of making the polymeric composition and articles containing the polymeric composition are also disclosed.

Abstract: A polymeric composition comprising at least 95 wt. % of a metallocene-catalyzed polypropylene, and at least one of a clarifying agent or a nucleating agent is disclosed. The polymeric composition can have a lower haze value when compared with a second polymeric composition that has the same components in the same wt. % amounts as the polymeric composition except that the polypropylene in the second polymeric composition is a Ziegler-Natta catalyzed polypropylene. The haze values can be determined by ASTM D1003 at a thickness of 50 mils.

Abstract: Color-stable rheology controlled polyolefin compositions and methods of making are described. A color-stable rheology controlled polyolefin composition can include a controlled rheology grade thermoplastic polyolefin, and an effective amount of a trisamide-based compound that imparts color-stability to the composition. The color-stable solid-state thermoplastic polyolefin composition can have a Hunter b value color change (Δb) rate of ≤0.03/day when stored at 93° C. for 50 days.

Abstract: An adhesive composition made from an elastomer and a tackifying resin. The tackifying resin includes a farnesene polymer or copolymer having the following properties: i) less than 10 weight percent of volatile organic compounds; ii) Mn between 300 Da and 1000 Da; iii) Mw between 400 Da and 3000 Da; iv) Mw/Mn between 1.00 and 3.00; v) Tg between −50° C. and 20° C.; and vi) viscosity between 400,000 cP and 1,000,000 cP at 25° C. A method of making the farnesene-based polymer or copolymer includes combining a farnesene monomer and a solvent and optionally adding one or more co-monomers selected from dienes, branched mono-olefins, and vinyl aromatics, to provide a monomer feed, and polymerizing the monomer feed by combining it with a Friedel-Crafts initiator in a vessel. The farnesene-based polymer or copolymer tackifier may be combined with one or more elastomers and one or more other tackifiers to form an adhesive composition.

Abstract: A polymer composition adapted for use in injection stretch blow molding may include a metallocene random propylene-based copolymer in the absence of a clarifier. The metallocene random propylene-based copolymer may exhibit a melting point of from 105° C. to less than 175° C., a recrystallization temperature ranging from 85° C. to 100° C. as measured by DSC, a microtacticity ranging from 89% to 99%, a molecular weight (Mw) ranging from 170,000 to 210,000, and a melt flow rate of from about 1 dg/min. to about 40 dg/min. A method of forming an injection stretch blow molded (ISBM) article may include providing the metallocene random propylene-based copolymer, injection molding the metallocene random propylene-based copolymer in the absence of a clarifier into a preform, and stretch-blowing the preform into an article.
