| 中文摘要: |
| 研究了预交联型CR溶胶组分的门尼粘度[ML(1+4)100 ℃]、凝胶组分的交联密度和溶胶/凝胶质量比对其加工性能的影响。结果表明，降低溶胶组分的门尼粘度、增大凝胶组分的交联密度和质量分数，都可改善预交联型CR的加工性能，使其表观粘度下降、挤出膨胀率减小、表面光滑度提高。 |
| 英文摘要: |
| The influence of the Mooney viscosity[ML(1+4)100 ℃] of sol component，the crosslinking density of gel component and the sol/gel mass ratio of the precrosslinked CR on its processibility was investigated.The results showed that the decrease of the Mooney viscosity of sol component and the increase of the crosslinking density and the mass proportion of gel component resulted in the improved processibility，the lower apparent viscosity and extrusion swell，and the smoother extrudate surface of precrosslinked CR. |
