Abstract: Polymerization of olefins in presence of a catalyst that comprises: (i) at least one complex (A) of a transition metal and a tridentate macrocyclic ligand (L) that has at least one substituent with donor function; and (ii) optionally one or more activator compounds (B). Independent claims are also included for the following: (a) catalyst system comprising (A) and (B); and (b) olefin polymers produced by this method.

Abstract: Oligomerization catalyst (A) for olefins comprises: (a) a chromium compound (I) and a ligand (L), or a preformed (I)-L complex; and (b) at least one activator (II). Oligomerization catalyst (A) for olefins comprises: (a) a chromium compound (I) and a ligand (L), or a preformed (I)-L complex; and (b) at least one activator (II). (I) has formula CrX3 and L has formula (VII). X = abstractable counterion; and R -R = hydrogen, organosilicon group or optionally substituted 1-30C organic group, and two geminal or vicinal R groups may together complete a 5- or 6-membered ring. Independent claims are also included for the following: (a) preparation of oligomers (III) of up to 30C by reacting at least one olefin at 0-150 deg C and 1-200 bar in presence of (A); (b) (III) produced this way; (c) oxo-alcohols (IV) produced from (III) by conventional hydroformylation; and (d) New compounds (1,3,5-tris(2-alkyl-substituted alkyl)-1,3,5-triazacyclohexane)CrCl3 (V).
