ABSTRACT:
A fluorinated dicarbonyl fluoride FOCCF(CF3)[OCF2CF(CF3)]lOCF2CF2O[CF(CF3)CF2O]mCF(CF3)COF (l+m is 30-130) is reacted with an aromatic amine XC6H4NHR1(R1is H, alkyl, or phenyl and X is I or Br) to obtain a fluorinated polyether compound of the following formula. The compound obtained is mixed with an aromatic boric ester, an organopalladium compound, and a basic inorganic or organic compound (and organophosphorus compound) to form a curable fluorinated polyether composition. This curable fluorinated polyether composition has satisfactory processability including moderate flowability at room temperature. It is applicable to various molding techniques including injection molding and RIM.
