Low boiling point (.72.C) and high critical temperature
(54.7.C) of VF necessitate high pressure polymerization similar to that
required
for polyethylene.
为什么low boiling point, high critical temp
要high pressure polymerization....??

氟乙烯的低沸点与高临界温度使其的聚合必须采取高压聚合的方法,如同合成(低密度
)聚乙烯一般。
高压法生产LDPE就是把乙烯加压到150~200MPa、180~200oC进行聚合的,此时的乙烯处
于临界温度之上,类似于液体。---高分子化学,潘祖仁,第三版,103页,化学工
业出版社,中国北京。
低沸点:常温下为气态;高临界温度:常压下单体浓度很低,因而生产效率很低,因此
必须疯狂加压,超过其临界温度之后,气体的密度等与液体类似,这样生产效率才高。
