PROBLEM TO BE SOLVED: To provide a polymer and lubricating compositions thereof capable of providing acceptable/improved shear stability, viscosity index control and low temperature viscosity.SOLUTION: The present invention relates to a novel polymer with pendant groups. The invention further provides a lubricating composition containing the polymer. The invention further provides a method and use of controlling viscosity index by supplying to an oil of lubricating viscosity the polymer with pendant groups. In one embodiment, the invention provides a lubricant composition comprising (a) an oil of lubricating viscosity, and (b) a polymer with pendant groups as defined above. In one embodiment, the invention provides a lubricant or lubricant concentrate obtained (or obtainable) by admixing the polymer of the invention with an oil of lubricating viscosity.

PROBLEM TO BE SOLVED: To provide a resin composition for fine pattern formation, which smoothly shrinks a resist pattern by a heat treatment, and is easily removed by subsequent treatment with an aqueous alkali solution. SOLUTION: The resin composition for fine pattern formation contains a resin, a crosslinking agent for crosslinking the resin, and a solvent and is used for microfabrication of a resist pattern. The resin contains a repeating unit (I) expressed by formula (1) and a repeating unit (II) expressed by formula (2). In the formula (1): R 1 represents a hydrogen atom or a methyl group; R 2 represents a single bond, a methylene group, a 2-5C chain or branched alkylene group, an -NH- group, an -O- group, a -COO- group, or a -CINH- group; R 3 each independently represents a hydrogen atom, a 1-6C saturated chain hydrocarbon group, a 3-8C monocyclic hydrocarbon group, or a 7-10C polycyclic hydrocarbon group; m represents 1 to 2; and n represents 0 to 2. In the second formula (2): R 1 represents a hydrogen atom or a methyl group; X represents a methylene group, a methylidene group, a 2-10C straight-chain or branched alkylene group, a 3-12C bivalent alicyclic hydrocarbon group, or a -NH- group; R 4 each independently represents 1-10C straight-chain or branched alkyl group, a 1-10C alkoxyl group, or a -O-Si=R' 3 group; R' each independently represents a 1-10C straight-chain or branched alkyl group or a 1-10C alkoxyl group.
