This invention discloses a category of fluorinated hydrocarbons chain melamine derivate which has end group of esterfunction/alkyl ether and its preparation. Fluorinated hydrocarbons chain melamine derivate has end group of esterfunction/ alkyl ether, of which structural formula is formula I, x,p,z=0,1,2;And x+y=2,p+q=2,e+z=2 but x,p,z does not equal 2 at the same time, among them Rf is formula II, Y=CF2OCH3 or COOCH3n=0-4. in condition of hydrolization/ oxidation, the composite fluorinated hydrocarbons chain melamine derivate that has end group of esterfunction/alkyl ether can be transformed into fluorinated hydrocarbons chain melamine derivate that has end group of reactive carboxy group, among them the end group of carboxylic acid can also participate reaction, form fluorinated hydrocarbons chain melamine derivate that has end group of Carboxylic salt. |
