Abstract: The effect of radiation conditions on the polymerization progress and none-strength temperature (NST) in the radiationinduced bulk polymerization of chloro-trifluoroethylene is presented in order to bring to light the regularity by which high quality products may be prepared. On changing the dose(D), dose rate(I)and radiation temperature (T), the kinetic progress remains smooth. One of the principal factors of controlling the product quality, i. e. NST, has been especially discussed and a relation between the factors which affect NST is obtained. This relation provides the basis for the selection of conditions for preparing products with various properties: when t≤20℃, NST = 1.75.l0-2.T0.9.I-0.39.D0.39; when t≥20℃, NST = 4.108.T-3.3.I-0.36.D0.39. The test results testify that the products from the bench-scale experiment have good thermal stability, excellent mechanical properties, reproducible quality, and high purity. The technological process is simple.

摘要： 本文着重介绍三氟氯乙烯本体辐射引发聚合中辐照条件对聚合进程及失强温度的影响,以阐明制取优质产品的规律。 当变化辐照剂量（D）,剂量率（I）和辐照温度（T）时,其聚合动力学进程仍然很平稳。 对该产品最主要的质量控制因素失强温度（NST）给予了专门讨论,求得了控制失强温度的各因素之间的关系式。该关系式对不同性能要求的辐射聚三氟氯乙烯产品,提供了选择条件的依据。 t≤20℃时, NST=1.75·10~（-2）T~（0.9）I~（-0.39）D~（0.39） t≥20℃时, NST=4·10~8T~（-3.3）I~（-0.36）D~（0.39） 通过扩大试验,证明所得产品热稳定性很好,机械性能优越,质量稳定,纯度高,工艺简单。
