The present invention provides polymers and methods of preparing the same. In certain embodiments, the polymers comprise acrylate repeating units that have been derivatized (e.g., reduced and/or substituted) to form new polymeric structures. In certain embodiments, the polymers described herein self-assemble to form well-defined nanostructures. In some instances, the nanostructures exhibit relatively small d-spacing (e.g., a d-spacing value of 10 nm or less). Due to their properties, the polymers described herein are useful in a variety of applications including functional materials and biomedical applications.

The present disclosure provides base stocks and processes for producing such basestocks by polymerizing internal olefins. The present disclosure further provides base stocks, comprising low molecular weight polyolefin products, having one or more of improved flow, low temperature properties, and thickening efficiency. The present disclosure further provides polyolefin products useful as base stocks and or diesel fuel. In at least one embodiment, a process includes introducing a feedstream comprising C.sub.4-C.sub.30 internal-olefins with a catalyst system comprising a nickel diimine catalyst optionally in the presence of a solvent. The method includes obtaining a C.sub.6-C.sub.100 polyolefin product having one or more of a carbon fraction of epsilon-carbons of from about 0.08 to about 0.3, as determined by .sup.13C NMR spectroscopy, based on the total carbon content of the polyolefin product.
