FLUORINATED POLYETHER COMPOUND, PROCESS FOR PRODUCING THE SAME, AND CURABLE COMPOSITION CONTAINING THE SAME

摘要

A fluorinated dicarbonyl fluoride FOCCF(CF<SUB>3</SUB>)[OCF<SUB>2</SUB>CF(CF<SUB>3</SUB>)]<SUB>l</SUB>OCF<SUB>2</SUB>CF<SUB>2</SUB>O[CF(CF<SUB>3</SUB>)CF<SUB>2</SUB>O]<SUB>m</SUB>CF(CF<SUB>3</SUB>)COF (l+m is 30-130) is reacted with an aromatic amine XC<SUB>6</SUB>H<SUB>4</SUB>NHR<SUP>1</SUP> (R<SUP>1</SUP> is 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.
