    摘要： PROBLEM TO BE SOLVED: To provide a monomer which is favorable in polymerizability, especially radical-polymerizability, forms a polymer with excellent optical characteristics by polymerization and useful as a base polymer of an antireflection film and a composition for a resist, and also to provide a fluorine containing polymer having the structural unit of the monomer, and further a composition for a photoresist. SOLUTION: A fluorine-containing ethylenic monomer has a hydroxyl group or a fluoroalkyl carbonyl group and is represented by formula, CX 1 X 2 =CX 3 -(Rf 3 )a-CRf 1 Rf 2 -OH, or formula, CX 1 X 2 =CX 3 -(Rf 3 )a-(C=O)Rf 1 wherein X 1 and X 2 are the same or different and each is H or F; X 3 is H, F, Cl or CF 3 ; Rf 1 and Rf 2 are the same or different and each is a 1-20C perfluoroalkyl group; Rf 3 is a fluorine-containing 1-40C alkylene group or a 1-100C fluorine-containing alkylene group with an ether bond having the total number of carbon atoms and oxygen atoms of two or more; a is 0 or 1. A fluorine-containing polymer has a structural unit of the monomer and further a composition for a photoresist is provided. COPYRIGHT: (C)2008,JPO&INPIT

    摘要： A process for producing a monoalkyl ether which comprises a first step of contacting the following components (A) and (B) :(A): an aqueous liquid phase containing:(a1) a C3-6 polyol having 3 or 4 hydroxyl groups, a palladium compound, a water-soluble tertiary phosphine or phosphite, and water; or (a2) a C3-6 polyol having 3 to 4 hydroxyl groups, a complex of palladium and a water-soluble tertiary phosphine or phosphite, and water, and (B): an oily liquid phase containing a conjugated diene, to give an alkadienyl ether containing an alkadienyl group resulting from dimerization of conjugated dienes; and a second step of hydrogenating the alkadienyl group in the alkadienyl ether in a hydrogen atmosphere in the presence of a catalyst containing an element selected from the Groups 8 to 10 elements of the periodic table. According to the process of the invention, monoalkyl ethers of polyols are produced selectively in a simple manner and advantageously from the economical viewpoint. The present process enables recovery and recycling of the catalyst.
