  • Publication number: 20230265222
    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.

  • Patent number: 10103334
    Abstract: The present disclosure provides a composition. In an embodiment, a composition is provided and comprises a Compound 1 shown below: For Compound 1, R1 through R24 are the same or different. R1 through R24 each is independently selected from the group consisting of hydrogen, unsubstituted hydrocarbyl, substituted hydrocarbyl, cyano, alkoxy, aryloxy, and NR?2. R? is hydrogen or hydrocarbyl; wherein two or more of adjacent R1 to R24 may optionally form one or more ring structures. The Component Z is selected from the group consisting Group Z-1, Group Z-2, Group Z-3, Group Z-4, Group Z-5, Group Z-6 and Group Z-7 shown below: For Compound 1, one or more hydrogen atoms may optionally be substituted with deuterium.
    Type: Grant
