| Abstract: |
| The properties between NR coagulated by microorganisms（NR-m） and acid（NR-a） were comparatively investigated.The results showed that，t10，t60 and t90 of NR-m compound were shorter than those of NR-a compound，the cross link density，modulus and tensile strength of NR-m vulcanizate were higher than those of NR-a vulcanizate.It indicated that the microbial coagulation process could promote the vulcanization of NR，which led to compact structure and better physical properties of NR-m vulcanizate compared with NR-a vulcanizate. |
