ABSTRACT:
The invention relates to a novel fluorinated pre-polymer and novel process steps in producing the same. The pre-polymers are quinoxaline materials derived by reaction of diketone linkage containing perfluoro-compounds with an aromatic diamine. The diketone is produced by a bis-ketone. The polychloroketone is produced by reacting a keto-ylid with a chlorinating agent, e.g., chlorine. The keto-ylid is produced by oxidatively dechlorinating a polychloroketone which may be a monoketone or reacting a phosphorane with an acid halide of a polyoxy-perfluoroalkylene oxide wherein the perfluoro-oxyalkylene group contains two or three carbon atoms, and there are present from two or twenty perfluoro-oxyalkylene units in the oligomer. The quinoxalines, the polychloroketones and the diketones hereof are novel products. Cross-linking may be effected with a free radical generator.
