Disclosed herein are star-shaped macromolecular structures comprising a hyper-branched silicon containing core grafted with a well-defined and controllable number of alkyl (methyl)acrylate (co)polymer arms. The presence of the robust inorganic core provides additional resilience against mechanical degradation and therefore enhanced additive life time. Control over the additive architecture was complemented by tunability of the length of the grafted polymers by making use of controlled radical based polymerization techniques. The performance of these novel inorganic-organic star-shaped hybrids were compared to traditional fully organic lubricant additives. Detailed analysis revealed the multi-functional character of the hybrids by simultaneously performing as bulk viscosity modifiers, boundary lubricant, and wear protectants while being dispersed in a commercially available base oil for automotive lubrication purposes. 1. A composition of matter , comprising:A star-shaped polymer comprising polymer chains grafted to or from a densely cross-linked silicon-containing hyperbranched core, wherein the densely cross-linked silicon-containing hyperbranched core comprises a silicate functionalized with one or more organic groups.2.

Methods are provided for producing a plurality of lubricant base oil products with an increased overall yield. Prior to the final hydrocracking stage for viscosity index uplift, a feed for making a lubricant base oil is fractionated in order to form at least a feed for making a lighter lubricant base oil and a feed for making a heavier lubricant base oil. The fractionation cut points are selected to so that the feed fraction for forming a light lubricant base oil has a higher Noack volatility and a lower viscosity than the desired targets for the lighter lubricant base oil. The feed fractions are then hydroprocessed separately to achieve desired properties. After hydroprocessing, a portion of the heavier base oil is blended into the light lubricant base oil to produce a blended base oil product. This returns the volatility and the viscosity of the blended base oil to the desired specifications. 1.

Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.
