| Abstract: |
| Natural latex was flocculated by natural drying，acid flocculation，inorganic salt coagulation
and thermal flocculation with seawater，and the effect of flocculation method on the properties of natural
rubber（NR） was studied. The results showed that the NR prepared by thermal flocculation using seawater
had higher tensile strength and elongation at break，which were 10. 7% and 38. 7% higher than those prepared
by natural drying，respectively，and the process properties，physical properties and dynamic mechanical
properties were better. |
