| Abstract: |
| The effect of the unsaturated polyester plasticizer，which was made by the degradation and repolymerization of waste polyester，and the curing system on the physical properties of unsaturated polyester-plasticized NBR vulcanizate were investigated.The results showed that the optimal plasticity of compound and the good hot and solvent resistance of vulcanizate were obtained when 20 phr of unsaturated polyester was used in NBR；the physical properties of unsaturated polyester-plasticized NBR cured with DCP/sulfur system were better than those cured with sulfur alone.The unsaturated polyester was a good plasticizer for NBR and compatible to NBR，and it could partly replace liquid ester plasticizer. |
