The effect of the radiation condition on the gel fraction, crosslinking regulation, and the network molecular weight were studied.
本文研究了辐射条件对硫化硅橡胶的凝胶分数、交联规律和交联网格分子量的影响。
Results showed that, the high boiling fraction yield in-creased by 2-3 percentages in weight by adding a small amount of high molecular active additive.
结果证明，加入少量高分子活性添加物可以提高馏分重量收率3个百分点以上。
When the PEO molecular weight increased, the gel fraction, the degree of swelling and the hardness of the PEO hydrogel films increased obviously as well.
当PEO分子量增加时，其水凝胶膜的凝胶分数、膨胀度和硬度亦明显增加。
