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 (R1 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.
Claims13
A fluorine-containing polyether compound represented by the following general formula:
- (wherein R1 is a hydrogen atom, an alkyl group having 1 to 3 carbon atoms, or a phenyl group, X is an iodine atom or a bromine atom, substitution position of X in the phenol group being a m- or p-position with respect to the NR1 bond substituent;
- and l and m are independently an integer of 10 or more, l+m being 30 to 130).
