Claim:
1. A process to prepare a utility fluid composition comprising: (1) contacting together ethylene and at least one coordination-insertion catalyst and, optionally, an alpha-olefin, wherein the coordination-insertion catalyst is a metal-ligand complex wherein the metal is selected from zirconium, hafnium and titanium, and has an ethylene/octene reactivity ratio up to 20, and a kinetic chain length up to 20 monomer units; in a continuously-fed backmixed reactor zone under conditions such that a mixture of at least two oligomer products is formed, the mixture including a hyperbranched oligomer having an average of at least 1.5 methine carbons per oligomer molecule, and at least one branched oligomer having an average number of carbons per molecule that is less than 20; (2) separating the hyperbranched oligomer from the branched oligomer; and (3) recovering the hyperbranched oligomer, the branched oligomer, or both.
