In the process of radiation crosslinking of silicone rubber (SR), the relationship between sol fraction (S) and irradiation dose (R) does not conform to Charlesby-Pinner's formula, because α=α,1,+α,0,R assumed by Charlesby can not be established for SR. Generally, the exact equation may be described as follows,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42648999&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649014&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649013&type=,Therefore, the relation between S and R for radiation crosslinking of SR can be obtained,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649015&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649017&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649016&type=,The influential factor is complicated for the dose exponent ,β, and molecular attraction between macromolecules and flexibility of main chain of polymer are important. If above factors were influenced,β, value can be changed. In this paper, the effect of molecular weight of polymer, side-group, filler and filler quantity on ,β, value and other crosslinking parameters were investigated.,Considering A is smaller in formula (2), we have,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649018&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649020&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649002&type=,By plotting with lnR ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649035&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649021&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649038&type=, against lnR, the value of B and β can be obtained from the intercept and the slope. Then, by plotting with ,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649022&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649043&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649042&type=, against R, the linear relationship between them can be obtained.,Also, by plotting with lnS against lnR, and when lnS→O, gelation dose (Rg) can be obtained.,Combining with,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649044&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649023&type=,http://html.publish.founderss.cn/rc-pub/api/common/picture?pictureId=42649045&type=,We can calculate the values of various crosslinking parameters
