Abstract: An interpolymer, which comprises at least one siloxane group, and prepared by polymerizing a mixture comprising one or more "addition polymerizable monomers" and at least one siloxane monomer, in the presence of a catalyst system comprising a Group 3-10 metal complex, and the siloxane monomer is selected from the following Formula 1: Aa-Si(Bb)(Cc)(Hh0)-O-(Si(Dd)(Ee)(Hh1)-O)x-Si(Ff)(Gg)(Hh2), described herein. An ethylene/siloxane interpolymer comprising at least one chemical unit of Structure 1, or at least one chemical unit of Structure 2, each described herein. A process to form an interpolymer, which comprises, in polymerized form, at least one siloxane monomer, or at least one silane monomer without a siloxane linkage, said process comprising polymerizing a mixture comprising one or more "addition polymerizable monomers" and at least one monomer of Formula 4, described herein, in the presence of a catalyst system comprising a metal complex from Formula A or Formula B, each described herein.

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.
