| Abstract: |
| The basic properties of imported Ti-BR from country A and country B，Ni-BR made in China，and their blends were compared through the test.The differences in the properties between Ti-BR and Ni-BR，as well as the differences in the properties beween the same catalyst-BR made by different producers were revealed.As far as the comprehensive properties，Ti-BR made in country A was significantly better than that made in country B，and Ni-BR made by factory B in China was significantly better than that made by factory A in China，which had been generally accepted as the best one in China.There were little difference in processesibility and no difference in physical properties when Ti-BR or Ni-BR was blended with NR in proper ratio.So，Ti-BR and Ni-BR could be replaced with each other in equal quantity in the rubber products，such as tires. |
