| Abstract: |
| A novel bioengineering rubber——poly(butanediol/propanediol/sebacic acid/itaconic acid)（PBPSI） copolyester was prepared with 1，3-propanediol，1，4-butanediol，sebacic acid and itaconic acid by melting polycondensation method，and the structure and properties of PBPSI were characterizedby FTIR，GPC and DSC.The results showed that，the molecular weight of PBPSI was high，the glass transition temperature was far lower than room temperature，and the physical properties and environmental stability were good. |
