Concentrates of linear, block copolymers having a polymer block derived from a monoalkenyl arene, covalently linked to one or more blocks of a hydrogenated derivative of a conjugated diene copolymer, dissolved in highly saturated diluent oil, wherein the size of the monoalkenyl arene block is controlled to provide an optimized level of incompatibility of the block copolymer in the selected diluent.

Provided are a lubricating material which is made of a non-fluorine-based compound and thus has a surface that is slippery enough for liquid such as water or oil, a lubricant-holding base material which holds a fluorine-based lubricant and thus can be used as a lubricating material, and methods for producing the same. A slippery film has a holding base and a lubricant. The holding base has pillar structure portions and fluorine-containing portions, and the fluorine-containing portions are provided on outer surfaces of a plurality of pillar portions in the pillar structure portion. The lubricant is a fluorine-based liquid, and the fluorine-containing portion has a CF bond. The lubricant is loaded into a region surrounded by a plurality of the pillar portions and is held in this region.

Provided herein are isoparaffins derived from hydrocarbon terpenes such as myrcene, ocimene and farnesene, and methods for making the same. In certain variations, the isoparaffins have utility as lubricant base stocks.
