| 中文摘要: |
| 采用聚酯合成厂的废聚酯经化学降解再聚合而成的不饱和聚酯作为增塑剂，加入到NBR中，通过对不饱和聚酯在NBR中的用量、增塑性能、硫化胶的耐热性能和耐溶剂性能及其硫化体系的研究表明，不饱和聚酯在NBR中的用量以20份为宜，添加不饱和聚酯的NBR胶料采用交联剂DCP/硫黄并用硫化体系的各项性能优于单独使用硫黄硫化体系。不饱和聚酯是一种良好的NBR增塑剂，与NBR的相容性良好，可部分替代液体酯类增塑剂。 |

| 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. |
