| Abstract: |
| The influence of the sol Mooney viscosity，the gel proportion and the accelerator type on the tensile strength of precrosslinked CR vulcanizate was studied.The results showed that the tensile strength of the precrosslinked CR vulcanizate decreased with the decrease of sol Mooney viscosity and the increase of gel proportion；the tensile strength improved significantly by adding 2 phr of antioxidant and using 1～2 phr of triethylene diamine instead of ethylene thiourea as accelerator. |
