Copolymers of vinylidine fluoride with hexafluoropropylene are prepared in aqueous dispersions using persulfate initiators. Hexafluoropropylene does not homopolymerize but it does copolymerize. This means that its content in the copolymer cannot exceed 50%. Preferred compositions appear to contain about 80% of vinylidine fluoride. The crosslinking reactions with diamines are not completely understood. It is believed that the reaction takes place in two steps. In the first one, a dehydrofluorination occurs ... [Pg.263]

In a study of the thermal decomposition of the copolymer of tri-fluorochloroethylene with vinylidine fluoride, it was established [34] that... [Pg.324]
