Abstract
Homo- and copolymers of 3-perfluoroalkyl-1,2-epoxypropane having a number average molecular weight between about 650 and 5000, preferably 1000 to 3000, are prepared by polymerizing 3-perfluoroalkyl-1,2-epoxypropane in the presence of an acidic catalyst and preferably a molecular weight controlling agent.
