determine master curve from temperature sweep

Hi,

I am trying to develop viscoeleastic model for a polymer material using the prony series. I know that the first step always is to construct the master curve. My data is give as Modulus vs temperature for a very large range of temperature. I only have 3 frequency which can not be used to fit the data to any curve. Is there a way to use the temperature sweep to determine the master curve instead of the frequency, I know that there is a duality between temperature and frequencies, I appreciate if you can help with some idea.

Thanks.

I have not attempted to do that. Feel free to try to work it out. If it is hard then I would perform additional frequency sweeps.
