| Abstract: |
| Zinc ethyl xanthate（ZEX），zinc n-butyl xanthate（ZBX）and sodium n-butyl xanthate
（SIX） were synthesized. The effects of alkyl chain length of xanthate and metal elements （zinc and
sodium）on natural latex vulcanization and mechanical properties of vulcanized film were investigated. The results showed that，thermal stability of accelerator ZBX was the best ，accelerator ZEX was the second，
and accelerator SIX was the worst. Zinc xanthate accelerators ZBX and ZEX had strong promotion effect
of vulcanization，while the effect of sodium xanthate accelerators SIX was weak. When the dosage of
accelerators ZBX or ZEX was 2 phr，the mechanical properties of the vulcanized film were the best. The
effect of zinc xanthate accelerator ZBX with longer alkyl chain was better than that of accelerator ZEX. |
