In this paper, the effect of irradiation temperature on sol fraction-dose relationship of tluoropolymers was studied. It was found that the increasing of irradiation temperature can result in the decreasing of β value of fluoropolymer, which increases the crosslinking probability of fluoropolymer. The relationship between crosslinking parameter βand irradiation temperature (Ti)of fluoropolymer is established as follows: β=2.2×10-3 Tg+4×10-4(Tg-Ti)+0.206. values of some tluoropolymers calculated from the above expression are in agreement with the experimental values.
