| Abstract: |
| The dynamic properties of molybdenum-catalyzed branched HVPBR（b-HVPBR） were studied by using rubber processing analyzer (RPA2000)，and compared with those of BR，ESBR and SSBR.The results showed that，in the range of experimental frequency，the storage modulus (G′) of b-HVPBR was the highest under low frequency，the loss modulus (G″) and loss factor ((tanδ) were smaller than those of BR，ESBR and SSBR，respectively,and their complex viscosity (η*) showed the same trait with that of pseudoplastic fluid.In the range of experimental temperature or strain，the G′ of b-HVPBR was higher than that of BR，ESBR and SSBR，and the (tanδ was smaller. |
