| Abstract: | Using the creep test a study was made on the vulcanization characteristics of NR/BR blend vulcanisate and its molecular chain scission and crosslink break during thermal oxidative aging. The test results were compared with those by equilibrium swelling method. Experiments show that such a type of test proves to be practical and feasible, with the features of simple devices and rapid and accurate measurements. |

| Keywords: | creep molecular chain scission and crosslink breaking crosslink density. |
