摘要：

Experimental data have revealed a correlation between the critical regimes of shear flow leading to spurt phenomenon and the critical regimes of elongational flow for the same materials [21,22]. For narrow-distributed polyisoprene PI-7, it was demonstrated that the Johnson-Segalman model is unable to match simultaneously the data in both flow regimes.
