| Abstract: |
| The properties of domestic neodymium polyisoprene rubber（Nd-IR） were investigated，and compared with those of natural rubber（NR） and Russian titanium polyisoprene rubber（SKI-3）.The results showed that，NR and its carbon black filled compound possessed strain-induced crystallization phenomenon，but the Nd-IR and its carbon black filled compound didn’t have that.The shape of the tensile stress-strain curve of Nd-IR vulcanizate was similar to that of vulcanized NR and Russian SKI-3.When the strain level was less than 600%，the stress of Nd-IR vulcanizate was slightly higher than that of Russian SKI-3 vulcanizate.The physical properties of Nd-IR and its carbon black filled compound and vulcanizate were similar to those of Russian SKI-3.The physical properties of Nd-IR vulcanizate could be similar to NR vulcanizate by appropriately increasing the addition level of accelerator. |
