In this paper, the relationship between sol fraction (S) and irradiation dose (R) in the radiation crosslinking of LLDPE/EVA blend and LLDPE/EPDM blend was studied. It was found that the Charlesby′s and Chen-liu-Tang′s expression, which are only in good agreement with radiation crosslinking of some polymers, do not fit to the radiation crosslinking of LLDPE/EVA and LLDPE/EPDM blends. A expression characterizing S-R relationship for polymer blends was established as follows: ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42652192&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42652194&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42652193&type=, and β,b,=∑W,i,β,i,. The results calculated from the above expression are in good agreement with ones obtained from the experiments.
