| 摘 要： | the relationship between intrinsic viscosityη] and yield strength σ?] of SBR-1500 raw rubberwas studied. It was found that the critical molecular weight for yielding varied with temperature.The critical yield temperature of SBR--1500 is 18℃, which is equivalent to transition temperature T'_(ll)as determined by linear expansion. The transition temperature T'_(ll) of SBR increased with styrenecontent in the sample.

| Abstract: | The relationship between intrinsic viscosityη] and yield strength σγ] of SBR-1500 raw rubberwas studied. It was found that the critical molecular weight for yielding varied with temperature.The critical yield temperature of SBR--1500 is 18℃, which is equivalent to transition temperature T'llas determined by linear expansion. The transition temperature T'll of SBR increased with styrenecontent in the sample. |
