Adamantane-containing esters as potential components of thermostable lubricating oils
摘要:
Some esters of dimethyladamantanedicarboxylic acids with aliphatic alcohols and the ester of dimethyladamantanedicarbinol with an aliphatic acid have been synthesized, and their properties have been studied; their viscosity-temperature properties and thermo-oxidative stability as potential components of high-temperature lubricating oils have been examined.

A series of diesters on the basis of 5,7-dimethyl-1,3-adamantanediol and 5,7-dimethyl-1,3- bis(hydroxymethyl)adamantane and C3–C10 aliphatic acids have been synthesized and their physicochemical and thermo-oxidative properties have been studied. The properties of the esters obtained have been compared to those of trimethylolpropane and neopentyl glycol esters.

Diacrylate and dimethacrylate esters corresponding to the formula ##STR1## wherein R and R' are hydrogen or methyl and A is either a sigma (.sigma.) bond; a (CH.sub.2).eta. radical where .eta. is an interger that may vary from one through four; or phenylene, or an alkyl derivative thereof. The new adamantane containing difunctional olefinic monomers can then be polymerized, or copolymerized with other acrylic type olefinic monomers to produce polymers with unusual physical properties, including unusual hardness, inertness to degradable agents, and resistance to heat.
A radiation-sensitive resin composition comprising an acid-labile group-containing resin obtained by living radical polymerization having a specific structure which is insoluble or scarcely soluble in alkali, but becomes alkali soluble by the action of an acid, and a photoacid generator, wherein the ratio of weight average molecular weight to number average molecular weight (weight average molecular weight/number average molecular weight) of the acid-labile group-containing-resin is smaller than 1.5.

An object of the present invention is to provide a novel fluorine-containing polymer, a radiation-sensitive resin composition for liquid immersion lithography which contains the fluorine-containing polymer, which leads to a pattern having an excellent shape and excellent depth of focus, wherein the amount of an eluted component in a liquid for liquid immersion lithography such as water that comes in contact with the resist during exposure in liquid immersion lithography is little, and which provides a larger receding contact angle between the resist film and the liquid for liquid immersion lithography such as water, and a method for purifying the fluorine-containing polymer. The present resin composition comprises a novel fluorine-containing polymer (A) containing repeating units represented by the general formulae (1) and (2) and having Mw of 1,000-50,000, a resin (B) having an acid-unstable group, a radiation-sensitive acid generator (C), a nitrogen-containing compound (D) and a solvent (E).
