| Abstract: | The microstructures of BR in different catalyst systems were measured with infrared spectrometry . The results showed that the contents of microstructure of BR were similar in same type of catalyst systems ,but different in different types . The long chain branching in polybutadiene and polyisoprene rubbers was measured with gel permeation chromatography coupled with an automatically recording capillary viscometer . The parameters of long chain branching and molecular weight changed with catalysts and polymerization conditions ,it was not so correct that the long chain branching in synthetic rubbers be defined only by the critical molecular weight or polymerization condition . |
