Abstract 
This disclosure provides for olefin wax oligomer compositions, methods of producing olefin wax oligomer composition, and methods for oligomerizing olefin waxes. This disclosure encompasses metallocene-based olefin wax oligomerization catalyst systems, including those that include a metallocene and an aluminoxane, a metallocene and a solid oxide chemically-treated with an electron withdrawing anion, and a metallocene, a solid oxide chemically-treated with an electron withdrawing anion, and an organoaluminum compound. The olefin wax oligomers prepared with these catalyst systems can decreased needle penetrations, increased viscosity, and an increased drop melt, making them useful as an additive in candles, stone polishes, liquid polishes, and mold release formulations.
TECHNICAL FIELD OF THE INVENTION
( OOlj This disclosure relates to the metailoeene catalyzed iigomorizalion of olefi n, waxes io form olefin wax oligomer compositions.
BACKGROUND Of TOE INVENTION
(0003j Mono-I-olefim (alpha-olefms). including ethylene, caa be oligomcmed with catalyst systems employing titanium, areonium, vanadium, ehroaiiaai or other metals impregnated on a variety of support materials, often in the presence of activators. These catalyst system may e useful for boi the homoo!igo eoxsitiori of ethylene, ccoh omerization of ethylene with comoaomers such as propylene, l^«huie«e, l-hexene, or higher alpha-oiefias, or in the homooiigomeriztaion olefin having more than. 2 carbon atoms. Because of the importance of preparing functional materials, there exists a need and a constant search to develop new olefin polymeriz ion catalysts, catalyst acti vation p rocesses, and methods of making and using catalysts that will provide enhanced catalytic activities, selectivifies, or new oligomer* c materials tailored to specific end uses.
[(KKHj One type of transition metal-based catalyst system utilizes metallocene compounds contacted with an activator such, as methyl aJuminoxane (MAO) to form an. oligonierizatioii catalyst system. There remain important challenges in developing catalysts and catalyst systems to ptoduce olefin wax oligomers having desired properties that can be tailored or maintained within a desired specification range.

fO005j This disclosure provides for olefin wax oligomer compositions, method of producing olefin wax oligomer composition, and methods for oligomcri siog olefin waxes. 10006! ^'f xe olefin wax oligomer composition comprises an olefin wax oligomer and olefin wax monomers. The olefin wax compositions have a decreased needle penetration, an increased kinematic visoeity , and/or increased drop rae!x point In an embodiment, the olefin wax oligomer has a 25 needle penetration at least 5 percent lower than tfee needle 5 penetration of the olefin wax monomer. In an embodiment, the olefin wax oligomer composition has 1.00 °C kinematic viscosity at least 20 percent higher than the olefin was monomer. In an embodiment, the olefin wax oligomer com osition, has drop melt point, in €, at least 5 percent higher than the olefin w x monomer.
| 00?| The disclosure further provides a method for ol.igoraerizi.ng an olefin wax S O comprising: a) contacting an olefin wax and a catalyst system, and b) oligomerizing the the olefin wa under oifgomerization conditions, in. an embodiment the catal st system comprises a metallocene. In some embodiments, the catalyst system comprises a metallocene and an alnmmoxaoe. hi other embodiments, the catalyst, system comprises a metallocene, a chemically-treated solid oxide and an organoahiminam compound.
.15 fOOOSJ A wide range of metailoeenes may be utilized in the catalyst systems for
oligomerizing an olefin wax. One examplary metallocene which ma be utilized in the catalyst system is a metallocene having the formula rR^R^.X^ wherein each X^"'' independently is a halogen, atom. R^Kl and R^! ' are substituted or unsttbstituted r -indenyi groups, and optionally R^{f 0} and R^u may be connected by a linking group. A second 0 exemplary metallocene which may be utilized in the catalyst system is a metallocene having the f mndaZr ^R^ ^ wherein each X independent!*- is a hatofien atom, R^Ui is a substituted or onsubstituted r -eycSopefttadienyl group, R^u is a substituted or unsnbstituted rj⁵~tluoreiiyi grou and Rⁱ and R^{f f} are connected by a linking group, A third exemplary metallocene which may be utilized in the catalyst system is a rneta!loceae
