    Abstract: PURPOSE:To provide the subject copolymer comprising diethyl fumarate structural units, etc., in a specific ratio, wide in a temperature range compatible with an alternative freon refrigerant R134a, high in viscosity index, excellent in rust prevention and thermal stability, and suitable as a lubricant for refrigerating machines, etc. CONSTITUTION:The objective copolymer comprises 5-45mol.% of structural units of formula I and structural units of formula II. The copolymer is produced by copolymerizing diethyl fumarate with dibutyl fumarate in the presence of a polymerization initiator such as 2,2'-azobisisobutyronitrile.

    Abstract: PURPOSE:To obtain the contact lens which has high oxygen permeability and can prevent the deposition of protein, lipid and inorg. matter, etc., onto the surface by using a specific polymer. CONSTITUTION:A copolymer formed by copolymerizing the 1-butene-2, 3, 4- triester tricarboxylate monomer expressed by formula I as a raw material monomer is incorporated into this contact lens. In the formula, R1 to R3 denote a hydrogen atom, 1 to 12C alkyl group, 1 to 12C alkenyl group, 3 to 12C cyclic alkyl group or aryl group, at least one group of which contain a fluorine atom; n, m and l respectively denote 0 to 4 integer. The number of the fluorine incorporated into at least one group of R1 to R3 is preferably >=3. The contact lens which has an excellent viewing power correcting effect, has the oxygen permeability to allow long-term continuous wearing and has the excellent shape stability, contamination resistance and durability is obtd. in this way.

    Abstract: PURPOSE:The titled composition, obtained by copolymerizing a quaternary ammonium salt with a monomer having unsaturated double bond capable of addition polymerization by irradiation with light, having improved dyeability for acid dyes, preservation stability, safety, etc., and useful as a color filter forming material, etc. CONSTITUTION:A composition obtained by copolymerizing a monomer expressed by formula I (R is H, CH3, etc.; X is -O- or -NH-; Y is 1-4C hydrocarbon; R -R are H or 1-4C alkyl; Z is anion) with a monomer expressed by formula II (R is H, C2H5, etc.) normally in the presence of a radical polymerization agent, preferably by a solution polymerization method. The above-mentioned copolymerization reaction is preferably carried out at 60-120 deg.C for 1-6hr. For example, methacryloyloxypropyltrimethylammonium chloride, etc., may be used as the compound expressed by formula I and, e.g. mono(2- methacryloyloxyethyl)maleate, etc., may be used as the compound expressed by formula II.
