Abstract

PURPOSE: To prepare the dimer and the trimer of hexafluoroepoxypropane, in high selectivity and yield, by polymerizing the compound in a specific diluent, in the presence of a catalyst.
CONSTITUTION: Hexafluoroepoxypropane is polymerized in an organic diluent composed of 1 part by weight of a polar aprotic solvent and about 0.01W1 part of an alkylene glycol or a polyalkylene glycol having an average molecular weight of about 200W1000, in the presence of a catalyst such as an alkali fluoride, a tert-amine, a tert-amine oxide, a quaternary ammonium self, etc. which are known polymerization catalysts. The polyalkylene glycol is pref. polyethylene glycol.
