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.
