Abstract
A method for polymerizing octafluoronaphthalene and the resulting perfluorocompounds prepared therefrom. Polymerization is accomplished by reacting the octafluoronaphthalene monomer with a mono or difluoroxyperfluoroalkane.
Claims2
As a compound, the copolymer having the formula ##STR13## wherein n is an integer of from 2 to 30.
A method for preparing a perfluorobicyclic polymer which comprises the steps of (A) forming a reaction mixture of (1) octafluoronaphthalene and (2) bis(fluoroxy) difluoromethane in a mole ratio of about 1:2 to 1:3;
- (B) heating said mixture within a vacuum for a period of time of about six hours at room temperature and progressively warming said mixture to 100.degree. C. for about two hours to effect a reaction therebetween;
- and (C) separating the resulting copolymer.
