Abstract: A supported catalyst system is based on a transition metal carbene including the moiety Ml=CR*) 2 , wherein M 1 is the transition metal and R* is hydrogen or a C1-C8 hydrocarbyl. The catalyst system can be supported on a metal oxide support such as silica or the catalyst can be self-supporting. Methods of making the catalyst system can involve precursors based on and/or reacted with aluminum alkyls, halides, and/or alkoxides. Methods of polymerizing cyclic olefins with the catalyst system can obtain polyalkenamers, cyclic olefin polymers, cyclic olefin copolymers, and other metathesis reaction products. The supported catalyst and/or monomer can be recovered and recycled to the polymerization reactor.

Abstract: The present disclosure provides a catalyst system comprising the product of a catalyst compound capable of making crystalline material (such as isotactic PP) and a second catalyst compound capable of making non-diene-containing-amorphous material and diene-containing- elastomeric material. The catalyst system of the present disclosure may further comprise a support material (or product thereof) having one or more of: a surface area of from 400 m2/g to 800 m2/g; an average pore diameter of 90 Angstroms or greater; an average particle size of 60 μm or greater; 40% or greater of the incremental pore volume comprising pores having a pore diameter larger than 100 Angstroms or greater; and sub-particles having an average particle size in the range of 0.01 μm to 5 μm. In another embodiment, a propylene polymer composition includes: isotactic polypropylene; 5 wt% or greater of atactic polypropylene, based on the weight of the composition; and an ethylene- propylene-diene terpolymer. The present disclosure further provides methods for forming propylene polymer compositions.
