Process for producing fluorinated copolymer having ion-exchange groups |
摘要 |
A fluorinated copolymer having 1 to 50 mole % of a component having functional group of carboxylic acid group or a group which can be converted to carboxylic acid group, is produced by copolymerizing a fluorinated ethylenic unsaturated monomer and a functional monomer having the functional group in the presence of a polymerization initiator source in 0 to 10 mole of an inert organic solvent per 1 mole of the functional monomer under the pressure of higher than 6 kg/cm2 whereby the copolymer having high molecular weight (TQ of higher than 150 DEG C) and an ion exchange capacity of 0.5 to 4 meq/g dry polymer is produced. |
