CONSTITUTION:The objective novel ester derivative of formula I [A is constituent derived from a monomer having copolymerizable double bond; R is group of formula II or III (R1 and R2 are each H or fluorine-substituted methyl; but not H simultaneously; R3 is H or lower alkyl); X is halogen or CH3; m is positive integer; n is 0 or positive integer, n/m being 0-2]. This ester derivative can be prepared by polymerization, e.g., of the corresponding acrylic ester monomer (e.g., alpha-chloroacrylic acid 1-phenyl-2,2,2-trifluoroethyl ester).

Abstract: PURPOSE:To readily obtain the titled compound in high yield under mild reaction condition, by the presence of a specific cation in the reaction system in reacting a fluorine-containing halogenated alkene with carbon dioxide in the presence of zinc in an organic solvent. CONSTITUTION:A compound expressed by formula I [R1-R3 are H or alkyl and at least one thereof is F, fluorine-containing alkyl (particularly 1-20C perfluoro or polyfluoro aliphatic group having straight chain or branched chain); X is Cl, Br or I] is reacted with carbon dioxide in the presence of zinc which is subjected or not subjected to surface treatment to give a reaction product, which is then hydrolyzed to produce a compound expressed by formula II. In the process, one or more cations selected from alkali metal ions, alkaline earth metal ions or ammonium ions exist in the above-mentioned reaction system to suppress side reaction and readily provided the aimed compound in high yield.

Abstract: PURPOSE:To obtain the titled polymer excellent in dry-etching resistance and useful as a resist material, a water repellent, a stainproof agent or a resin modifier, comprising units each containing a trifluoromethyl group in the alphaposition and a benzene ring in the ester moiety. CONSTITUTION:Potassium alpha-trifluoromethylacrylate is reacted with an alpha- substituted benzyl bromide to obtain an alpha-trifluoromethyl acrylate monomer (e.g., benzyl alpha-trifluoromethylacrylate). This monomer is polymerized at -80-100 deg.C in an organic solvent (e.g., toluene) in the presence of a catalyst (e.g., t-butoxypotassium) to obtain the titled polymer having repeating units each of which has a trifluoromethyl group in the alpha position and a benzene ring in the ester moiety and represented by the formula (wherein R are each H or a lower alkyl and n is 20-20,000).

Abstract: PURPOSE:To enhance sensitivity and resolution to electron beams and X-rays by using a polymer composed of specified repeating units as a resist material. CONSTITUTION:The polymer to be used as the resist is composed of the repeating units represented by formula I in which R1 is methyl, fluorinated methyl, or the like; R2 is 3,5-difluorophenyl or the like; each of R3 and R4 is H, alkyl, or the like; and R5 is optionally fluorinated phenyl. This polymer is obtained by homopolymerizing alpha-substituted acrylate represented by formula II, which is obtain by reacting an alpha-substituted acrylic acid with a chlorinating agent, such as thionyl chloride, phosphorus pentachloride, or oxalyl chloride to synthesize the alpha-substituted acryloyl chloride, and further reacting it with alcohol having a benzene ring and containing an fluorine atom in the presence of a base, thus permitting the obtained resist material to be enhance in sensitivity and resolution to electron beams and X-ray, and superior in dry etching resistance.
