摘要： Homo- or copolymers of allyl fluoride in which the fluorine content is at least 85% of the theoretical value are obtained using as initiator a compound of the formula in which R1, R2, R3 are each a hydrocarbon radical. The preferred initiator is azobisisobutyronitrile. The examples describe copolymers with vinyl chloride and vinyl acetate.ALSO:Allyl fluoride is obtained by reacting potassium fluoride with allyl chloride in diethylene glycol. The allyl fluoride may be purified by distillation.
