    摘要： PURPOSE:To provide a new compound useful as a reactive diluent having low odor, low volatility and high dilutability and usable for an actinic radiation curable resin such as electron-curable resin and as a modifier or a cross-linking agent for various resins. CONSTITUTION:New compounds 1,9-nonanediol monovinyl ether and 1,9- nonanediol divinyl ether expressed by the formulas HO-CH2(CH2)7-CH2-O-CH= CH2 and H2C=CH-O-CH2(CH2)7-CH2-O-CH=CH2. The compounds can be produced e.g. by heating and melting 1,9-nonanediol in a vessel, adding about 19-380 m-mol of an alkaline compound as a catalyst to 1mol of the 1,9-nonanediol, replacing the atmosphere in the vessel with nitrogen gas, reacting the components under a pressure of about 3-10kg/cm at about 110-140 deg.C while introducing acetylene into the vessel, adding distilled water to the reaction mixture after the completion of the reaction and distilling the mixture under reduced pressure. 1,9-Nonanediol monovinyl ether is distilled out together with steam and then 1,9-nonanediol divinyl ether is distilled out.

    摘要： NEW MATERIAL:A compound expressed by formula I [R is H or COOR (R is CH3 or C2H5), phenyl or formula II (R is H or R ; R is H or acetyl)]. EXAMPLE:2-(3-Phenyl-2,5-norbornadieneoxycarbonyl)ethyl vinyl ether. USE:Useful as a monomer for producing new polymers, having 2000-500000 number-average molecular weight and composed of recurring units expressed by formula III and other recurring units having 1,2-ethylenic bonds and capable of providing new excellent polymers having flexibility and tough properties using at least 5wt.% compound expressed by formula I and 0-95wt.% compound having vinyl polymerizability. PREPARATION:A vinyl ether compound expressed by formula IV is reacted with a norbornadiene expressed by formula V (M is alkali metal), as necessary, in the presence of a phase-transfer catalyst such as tetraethylammonium bromide in or without a solvent at 0-120 deg.C under ordinary pressure to afford the objective compound expressed by formula I.

    摘要： PURPOSE:To obtain the present novel polymer optically crosslinkable, useful as a sheath material for optical fiber, having specific molecular weight, excellent durability, water and oil repellency and low refractive index comprising a (meth) acrylic acid ester of fluorine-containing polyvinyl ether. CONSTITUTION:A solution of acryloyloxyethyl vinyl ether in 'TRIFLON(R) is reacted with a solution of anhydrous hydroiodic acid in n-hexane in an inert atmosphere at -25 deg.C and then with a solution of an fluorine-containing alkyloxyethyl vinyl ether in 'TRIFLON'(R) and a solution of iodine in toluene. Then, the reaction is stopped by adding methanol to the reaction solution, the reaction solution is treated with sodium thiosulfate and the reaction product is extracted with 'TRIFLON(R), etc., to give the aimed polymer shown by the formula (R is H, lower alkyl or lower polyfluoroalkyl; R is polyfluoroalkyl; R is H or lower alkyl; Y is lower alkyl, acryloyloxyethyl, etc.; n is >=3) having >=1,000 weight-average molecular weight.

    摘要： PURPOSE: To improve the residual rate of epoxy groups, stability with time, etc., by adjusting the pH value of the reaction solution to a specified range by using a buffer in producing a polymer latex by emulsion-polymerizing an epoxy group- containing vinyl monomer.
    CONSTITUTION: A mixture is formed from an epoxy group-containing vinyl monomer such as glycidyl acrylate or vinyl glycidyl ether, a copolymerizable monomer (e.g., ethyl acrylate), a polymerization initiator (e.g., K
    2 S
    2 O
    8 ), a surfactant (e.g., sodium dodecylbenzenesulfonate), water, etc. Then, a buffer capable of adjusting the pH of the reaction solution to 5W8 is added, and the reaction solution is emulsion-polymerized while the pH of the solution is being maintained at 5W8 to obtain the purpose polymer latex. Preferred buffers include primary sodium phosphate and secondary sodium phosphate, and its concentration is preferably about 0.001W2mol/wt%, based on the total monomer used.
