摘要： 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.

摘要： A composition includes a core-shell polyorganosiloxane particle having an average particle size in a range of 50-150 nanometers, the core-shell polyorganosiloxane particle comprising: (a) a core with a core polyorganosilsesquioxane; and (b) a shell coating the core comprises a shell polyorganosiloxane that is a functionalized polyorganosiloxane different from the core poly-organosilsesquioxane; where the shell is greater than zero and less than 20 weight-percent of the core-shell polysiloxane particle weight and less than 25 percent of the particle diameter.
