Problem 11.2 In Figure 11.30 we observe that the viscosities of the 70/30 nylon 6/PET blend lie between those of neat nylon 6 and PET at 0.5s1. However, at >0.5s1 the viscosities of both 70/30 and 30/70 nylon 6/PET blends lie below those of neat nylon 6 and PET. You may assume that the minor component in each blend forms the discrete phase (drops) and the major component forms the continuous phase. Explain why the viscosities of the 70/30 nylon 6/PET blend lie between those of neat nylon 6 and PET at 0.5s1. Explain why the viscosities of the 30/70 nylon 6/PET blend lie below those of neat nylon and PET over the entire range of shear rates tested
