A hexadentate ligand for polymerization of olefins including chemical structure(I) is provided: R1, R2, and R3 of chemical structure (I) are each independently hydrogen, hydrocarbyl, substituted hydrocarbyl, or an inert functional group; R4 and R5 are each independently hydrogen, hydrocarbyl, an inert functional group, or substituted hydrocarbyl; Y1 is a structural bridge; and W, Y1, and Z are independently hydrogen, hydrocarbyl, an inert functional group, or substituted hydrocarbyl having from about 0 to about 30 carbon atoms. In another embodiment of chemical structure I, W, Y1, and Z are selected to produce chemical structure (II): R6, R7, R8, R9, and R10 of chemical structure (II) are each independently hydrogen, hydrocarbyl, an inert functional group, or substituted hydrocarbyl; RA, RB, RC, and RD are each independently hydrogen, fluorine, an inert functional group, a primary carbon group, a secondary carbon group, or a tertiary carbon group; Y2 is a structural bridge between two halves of the structure, and more particularly may be a bond, a hydrocarbyl group comprising from about 0 to about 20 carbon atoms, methylene (CH2), ethylene (C2H4), or an inert functional group; and any two of RA, R6, R7, RB, RC, R8, R9, R10, and RD, or any portion of Y2, vicinal to one another, taken together may form a ring.

L'invention concerne un ligand hexadenté pour la polymérisation d'oléfines ayant la structure chimique (I). R1, R2, et R3 y sont chacun indépendamment hydrogène, hydrocarbyle, hydrocarbyle substitué, ou un groupe fonctionnel inerte; R4 et R5 sont chacun indépendamment hydrogène, hydrocarbyle, un groupe fonctionnel inerte, ou hydrocarbyle substitué; Y1 est un pont structurel; et W, Y1, et Z sont chacun indépendamment hydrogène, hydrocarbyle, un groupe fonctionnel inerte, ou hydrocarbyle substitué ayant entre environ 0 et environ 30 atomes de carbone. Selon une autre variante de ladite structure, I, W, Y¿1?, et Z sont choisis pour donner une structure chimique (II). R¿6?, R¿7?, R¿8?, R¿9?, et R¿10? y sont chacun indépendamment hydrogène, hydrocarbyle, un groupe fonctionnel inerte ou hydrocarbyle substitué; R<SB>A</SB>, R<SB>B</SB>, R<SB>C</SB>, et R<SB>D</SB> sont chacun indépendamment hydrogène, fluor, un groupe fonctionnel inerte, un groupe carbone primaire, un groupe carbone secondaire, ou un groupe carbone tertiaire; Y¿2? est un pont structurel entre deux moitiés de la structure, et plus particulièrement éventuellement une liaison, un groupe hydrocarbyle comprenant entre environ 0 et environ 20 atomes de carbone, methylène (CH¿2?), éthylène (C¿2?H¿4?), ou un groupe fonctionnel inerte; et l'un quelconque de R<SB>A</SB>, R¿6?, R¿7?, R<SB>B</SB>, R<SB>C</SB>, R¿8?, R¿9?, R¿10?, et R<SB>D</SB>, ou une partie quelconque de Y¿2?, occupant une position rapprochée, peuvent former ensemble une chaîne.
