A STUDY ON THE YIELD STRENGTH OF SBR RAW RUBBER

Received Date: 14 October 1983

The relationship between intrinsic viscosity[η] 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.
