Process for preparing fluorine-containing polymers

摘要: A PROCESS HAVING BENEFICIAL UTILITY IN THE MANUFACTURE OF FLUORINE-CONTAINING POLYMERS FROM HFPO (HEXAFLUOROPROPYLENE OXIDE), ESPECIALLY USEFUL FOR APPLICATIONS REQUIRING DIFUNCTIONAL POLYMER PRODUCTS THAT ARE SUBSTANTIALLY FREE MONOFUNCTIONAL POLYMER. POLYMERIZATION EMPLOYS MIXTURE AND CATALYST; CATALYST, WHICH PREFERABLY CESIUM FLUORIDE, IS MADE UP SOLUTION AN ETHYLENE GLYCOL ETHER PARTICULAR ORGANIC COMPOUND CONTAINING BOTH FLUORINE. REACTION ZONE AT ABOUT -30 TO -60* C., IT CONTAINS HEXAFLUOROPROPYLENE OR LIKE AS SOLVENT
