Perfluoro-1,3-dioxole is a useful monomer, which polymerizes to either amorphous or liquid homopolymers and copolymerizes with tetrafluoroethylene as well as with other monomers to both crystalline and amorphous copolymers having one or more such comonomers incorporated therein. Amorphous homopolymers and copolymers of perfluoro-1,3-dioxole are useful in such applications as glazing for reactors for hydrogen fluoride reactions. Amorphous homopolymers and amorphous or crystalline copolymers form self-supporting films and can be used for coatings and linings which are inert to most chemicals and are stain and weather resistant and as dielectrics for electrical and electronic equipment. Liquid homopolymers can be used as hydraulic fluids and heat exchange media.
全氟-1,3-二噁英是一种有用的单体,可以聚合成无定形或液态的同聚物,并与四氟乙烯以及其他单体共聚,形成结晶和无定形的共聚物,其中含有一个或多个这样的共聚单体。全氟-1,3-二噁英的无定形同聚物和共聚物可用于反应氢氟酸的反应器的镀膜等应用中。全氟-1,3-二噁英的无定形同聚物和无定形或结晶的共聚物形成自支撑薄膜,可用于对大多数化学品惰性的涂层和衬里,并具有防污和耐候性,也可用作电气和电子设备的介电材料。液态同聚物可用作液压油和换热介质。
