Zusammenfassung: | NEW MATERIAL:A fluorine-containing carboxylic acid or ester thereof expressed by the formula [A is expressed by formula I or II (Rf is 1-11C fluoroalkyl; Rf' is CF3; R3 is CH3 or CF3; n is 1, 2 or 3); R1 and R2 are H, F, RfCH=CH or Rf'R3C=CH, at least one of R1 and R2 is expressed by formula III (R4 is H or lower alkyl; m is an integer 4-11)]. EXAMPLE:The compound expressed by formula IV. USE:An emulsion paint and a raw material for coating materials, plastics, fibers, surfactants or emulsifying agents having antistaining properties, etc. PREPARATION:A cyclic ketone expressed by formula V is reacted with hydrogen peroxide to form a cyclic ketone peroxide, which is then reacted with a monomer expressed by the formula RfCH=CH2 or Rf'R3C=CH2 (R3 is CH3) in the presence of a ferrous salt to afford the aimed compound expressed by the formula R1-A-R2 (R2 is CH3). |
