摘要

The structure effects of polymers on the relationship between sol fraction and radiation dose arediscussed in detail. In consideration of the deviation of experimental results from Charlesby-Pin-ner's and Chen-Liu-Tang's expressions relating sol fraction to radiation dose

we introduced an ex-ponent β concerned with the structure and property parameters of a polymer (glass transition tem-perature Tg and molecular internal rotating steric factor δ) and assumed that the fracture density isproportional to Rβ(R is radiation dose).Thus

a general expression

formula (9)

relating sol fraction to radiation dose is derived.When β=1 and β=0.5

this expression is reduced to the abpve-said two expressions

Using this general expression

the experimental data of a number of polymers are treated.It is shown that the expression is in good agreement with the experimental results

β value is in the range of 0.5 to 1.0.
