| Abstract: | The effect of heating on the physical properties of ENR and NR was investigated.The results showed that as the heating lasted,the Mooney viscosity of ENR and the modulus of its vulcanizate increased,and the tensile strength and elongation at break of vulcanizate decreased;and the Mooney viscosity of NR and the modulus and elongation at break of its vulcanizate changed little,and the tensile strength of vulcanizate decreased slightly. |

| Keywords: | ENR NR heating Mooney viscosity physical properties |
