Abstract: Propylene-based elastomer compositions that include a blend of a majority polymer fraction having a higher Mw and a minority polymer fraction having a lower Mw, methods of making same, and hot melt adhesives including such compositions. The polymer blend compositions can include: a major polymer fraction having a Mw of about 100,000 to about 300,000 and a melt flow rate of about 0.1 g/10 min to about 70.0 g/10 min, according to ASTM D1238; and a minor polymer fraction having a Mw of about 5,000 to about 60,000 and a Brookfield viscosity of about 500 cP to about 50,000 cP, according to ASTM D-3236 (190° C.), wherein an amount of the at least one other polyolefin comonomer in the minor polymer fraction is at least 7 wt % less than an amount of the at least one other polyolefin comonomer in the major polymer fraction.

Abstract: This invention relates to a process for producing a polymer of a cyclic olefin and a linear mono-olefin, the process comprising contacting at least one C5 based cyclic olefin with at least one linear mono-olefin having from two to twenty carbon atoms in the presence of an alkene metathesis catalyst, and the polymer so produced.

Abstract: This invention relates to a metathesis catalyst compound comprising an asymmetrically substituted N-heterocyclic carbene (NHC) metathesis catalyst and a process to make linear alpha-olefins comprising contacting a feed material and an optional alkene (such as ethylene) with said catalyst, where the feed material is a triacylglyceride, fatty acid, fatty acid alkyl ester, and/or fatty acid ester, typically derived from biodiesel.

Abstract: This invention relates to a Group 8 metal containing catalyst compound for the metathesis of olefins. This invention also relates to process to make alphaolefins comprising contacting an olefin, such as ethylene, with a feed oil containing a triacylglyceride (typically a fatty acid ester (such as methyl oleate)) with a Group 8 metal containing catalyst compound. The fatty acid ester may be a fatty acid methyl ester derived from biodiesel.

Abstract: This invention relates to a polymer of a cyclic olefin and a vinyl terminated macromonomer, and processes for the production thereof.

Abstract: This invention relates to processes for increasing the viscosity of an oligomer composition including contacting the oligomer composition comprising one or more vinyl terminated oligomer with a supported mixed metal oxide catalyst; wherein the contacting causes the reaction of the vinyl terminated oligomers; and producing a product oligomer composition having a higher viscosity than the oligomer composition.
