ABSTRACT By means of radicalic starters, fluoroolefins are polymerized in the presence of perfluoropolyethers containing, at one or at both ends, a bromine atom, in such amounts that the wieght ratio between perfluoropolyethers and fluorinated olefins in the resulting product ranges from 4/1 to 1/50. The bromine-containing perfluoropolyethers to be utilized in the process have a molecular weight from 400 to 10,000 and preferably from 600 to 8,000. The resulting polymeric products comprise sequences of perfluoroolefinic units and perfluoropolyether blocks. The present invention makes it possible to modify the macromolecular structure of known types of polymers and advantageously vary the properties thereof. The polymers are useful in the vulcanization of rubber.
