Abstract

In this paper

the gamma-radiation effect on random 1

2-polybutadiene was studied by measureing sol fraction

double bonds conversion (by IR) etc. The network formation of irradiated unsaturated polymer was analysed and discussed theoretically. For the random chain reaction of irradiation 1

2-PB the relation between sol fraction S and radiation dose R/or crosslinking index

γ/

can be expressed as follows:

https://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=68635416&type=

and from this

some information on crosslinking of irradiated unsaturated polymer system can be obtained.

For the random 1

2-PB with high 1

2-unit contet

both intermolecular crosslinking and intramolecular cyclization take place simultaneously during irradiation

and cyclization reaction exceeds crosslinking formation G(cy)>G(c. 1). The effect of molecular weight of irradiated sample on radiation crosslinking was also discussed.
