Abstract

A novel process for the production of fluorine-containing multi-component copolymers having functional groups is disclosed, which process is characterized in that tetrafluoroethylene having the formula: CF.sub.2 .dbd.CF.sub.2 ; one or two or more .alpha.,.beta.,.beta.-trifluoroacrylate having the generic formula: CF.sub.2 .dbd.CFCOOC.sub.n H.sub.2n+1 wherein n represents an integer of 1 or greater; and one or two or more .alpha.-olefin having the generic formula: ##STR1## wherein j and m each independently represents an integer of 0 to 11 inclusive; are copolymerized with one another in the presence of a radical initiator. The resultant interpolymer is hydrolyzed and cross-linked using ionizing radiation.
