| 摘 要： | 用 GPC-自动粘度计联用法和过滤法研究了镍系顺式1,4-聚丁二烯合成橡胶中的长链支化与凝胶含量之间的关系,结果表明凝胶的产生同长链支化的存在有密切关系,这两种结构含量之间几乎成线性关系。

The Relationship between Long·Chain Branch and Gel of Polybutadiene |
| |
| Abstract: | The relationship of long chain branch with gel in polybutadiene was discussedin this paper.The parameter of long chain branch was obtained by means of thetechnique of GPC coupled with viscometer and the amount of gel was determinedby evaporating the solvent and weighing the solute.The mechanism ot gel formation was discussed in detail.The amount of gelwas found to be affected by the frequency of long chain branching.The formationof micro gel was especially promoted by the presence of long chain branch andthe gel is obtained trom collecting the microgel. |
