【Abstract】 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.更多还原
