The present disclosure provides a thermoplastic olefinic composition made from or containing: (A) a first polymer composition made from or containing a homopolymer polypropylene; (B) a second polymer composition made from or containing a polypropylene polymer grafted with an unsaturated monomer; (C) a third polymer composition made from or containing a first elastomeric ethylene copolymer; and (D) a carbon fiber composition made from or containing a carbon fiber coupled with a sizing composition. Optionally, the thermoplastic olefinic composition may be further made from or contain (a) a fourth polymer composition made from or containing a heterophasic polypropylene copolymer, (b) a fifth polymer composition made from or containing a second elastomeric ethylene composition, (c) an inorganic filler composition, (d) an additives composition, or (e) any combination of these components. The thermoplastic olefinic composition is suitable for use as a metal-replacement component, including automotive components.

The present disclosure provides metallocene catalysts for use in polymerization processes. Such catalysts may be used to generate polymers with low branching and high molecular weights. Also, the present disclosure provides methods of bimodal polymerization resulting in a duality of average molecular weight polymers being simultaneously produced. In the system, the size of the polymers produced can be controlled by modifying the type and amount of catalyst activator.

The present disclosure relates to metallocene catalyst and the use thereof to make polyolefins. In particular, the present disclosure relates to silyl-functionalized metallocene catalyst and the use of the silyl-functionalized metallocene catalyst to polymerize olefins and yield a polyolefin. Also, the present disclosure relates to a method for producing a polyolefin comprising at least the step of contacting an olefin with a metallocene catalyst to produce a polyolefin. In particular, the present disclosure provides a method for producing a polyolefin comprising the step of contacting an olefin with a silyl-functionalized metallocene catalyst.


The present disclosure relates to metallocene catalysts for use in polymerization processes. Such catalysis may be used to generate long chain polymers with low long chain branching and high molecular weights. Additionally, the size of the polymers produced can be controlled by modifying the ratio of MAO or other activator to metallocene catalyst.
