Hi,

I run rotational rheology, frequency sweep in the range of 0.01-100 rad/s, on PHBV samples having the various molecular weight and PDI, and also various HV content at a temperature higher than the melting point of the samples. the results do not approve the other researcher's papers. it is expected the samples having higher Mw and PDI show the higher zero shear viscosity, and the samples having higher HV content show lower zero shear viscosity. but the results follow none of these scientific facts. do you have any idea about interpreting the results?

Thank you
