Entanglement Effects on Craze Fibril Breakdown

The results in Fig. 37 reinforce how important the entanglements are for fibril stability It shows the results for measured for blends with x = 0.3 as a 

While one might suppose that one could correlate the fibril stability for the mono-disperse PS s and the PS blends by using the number-average, viscosity-average or
