| 英文摘要 | The effects of weight-average molecular (M (w) ), molecular weight distribution (MWD), and isotacticity on the linear viscoelastic behavior of polybutene-1 melts are studied. It is observed that the linear viscoelastic region becomes slightly narrower with increasing frequency. In frequency sweeps, the transition of the polymer melts flow from Newtonian flow to power-law flow can be observed. The melts with higher M (w) and/or broader MWD, as well as higher isotacticity exhibit higher complex viscosity, zero shear viscosity, viscoelasticity moduli, relaxation modulus, broader transition zone, while lower critical shear rate, non-Newtonian index, and the frequency at which elasticity begins to play an important role. The relationship of zero shear viscosity on M (w) has been established, which agrees with the classical power law. Furthermore, it is found that the cross-over frequency decreases with increasing M (w) and the cross-over modulus increases with narrowing MWD. |
