Abstract:
A polymer which is the product of free radically copolymerizing, in the presence of an organic iodide, a reaction mixture of monomers comprising tetrafluoroethylene, a compound of the formula CF.sub.2 .dbd.CFOR.sup.1, wherein R.sup.1 is an n-alkyl containing 1 to 6 carbon atoms, and, optionally, other free radically copolymerizable monomers, provided that:said polymer contains about 0.1 to about 5 percent by weight of iodine; andrepeat unit (I), derived from tetrafluoroethylene, and repeat unit (II), derived from a compound of the formula CF.sub.2 .dbd.CFOR.sup.1, are at least 50 mole percent of the repeat units of said polymer.
