摘要
通过对液体氟弹性体(低分子量氟弹性体)的分子量及其分布、共聚单体组成和微观结构的分析,发现二溴四氟 乙烷对于液体氟弹性体的聚合反应具有明显的分子量调节作用,同时研究了液体氟弹性体聚合物的端基组成和序列结构。
Through the characterization of the molecular weight and distribution, comonomer content, micro-structure of liquid fluoroelastomer (low molecular weight fluoroelastomer) , it is found that 1,2- dibromo -1,1,2, 2 - tetrafluoro - ethane has a sufficient effect on the molecular weight of liquid fluoroelastomer in the polymerization. The chemistry structures of end groups and sequence structure of liquid fluoroelastomer are also characterized.
