| 20120095275 | Production of 1-Butene and Propylene From Ethylene - A process for producing propylene and 1-butene is disclosed. The process comprises dimerizing ethylene in the presence of a dimerization catalyst to produce a dimerization mixture comprising 1-butene and 2-butenes. The dimerization mixture is distilled to produce a 1-butene stream containing 1-butene and ethylene, a 2-butenes stream, and a heavy stream. The 2-butenes stream is reacted with ethylene in the presence of a metathesis catalyst to produce a metathesis mixture comprising propylene, ethylene, and 2-butenes. Propylene is separated from the metathesis mixture. | 04-19-2012 |

| 20110159297 | Multilayer structures with common tie layer - Multilayer structures having layers of a styrene polymer, polyethylene, propylene polymer, and common tie layers of a styrene-butadiene-styrene triblock copolymer-containing adhesive. | 06-30-2011 |
| 20110129667 | Adhesive compositions - Adhesive compositions comprising a first copolymer of butene-1 and propylene; a second copolymer of ethylene and a comonomer selected from butene-1, hexene-1, and octene-1; a polyolefin grafted with an ethylenically unsaturated carboxylic acid or acid derivative; and an olefin polymer resin, and multilayer structures comprising the adhesive composition. | 06-02-2011 |
| 20110129666 | Butene copolymer-containing adhesive blends - Compositions suitable for use as adhesives in multi-layer structures. The compositions comprise a blend of an ethylene copolymer of butene and a propylene-based polymer; a polyolefin grafted with an ethylenically unsaturated carboxylic acid or acid derivative; and an olefin polymer resin different than the ethylene copolymer of butene, the propylene-based polymer and the grafted polyolefin. | 06-02-2011 |
| 20110027583 | Adhesive compositions - Adhesive compositions suitable for use as tie-layer adhesives in multi-layer films and sheets are provided. The adhesive compositions contain an olefin polymer base resin, a modified polyolefin and a paraffinic liquid hydrocarbon. | 02-03-2011 |
| 20110015323 | Polyethylene compositions comprising a polar phenolic antioxidant and reduced dissipation factor, and methods thereof - A polyethylene composition comprising about 0.0001% to less than 0.22% by weight of a polar phenolic antioxidant, the polar phenolic antioxidant comprising a polar phenolic moiety and a non-polar C | 01-20-2011 |
