I just wanted to make sure that the last sentence is worded correctly. It says that "time-temperature superposition avoids the inefficiency of measuring a polymers behavior over long periods of time at a specified temperature by utilizing the fact that at lower temperatures and shorter time the polymer will behave the same."

Shouldn't it say that at higher temperatures and shorter time the polymer will behave the same? In other words, that by testing for a shorter period of time at an elevated temperature is equivalent to testing at a lower temperature but for a much longer period of time?

Hi Dimitry,

I graduated Polymer Science and Technology about 20 years ago and I think that you're right testing at higher temperatures is equivalent to testing for a longer time, testing at a lower temperature is equivalent to testing at a higher rate. Biofuelsimon (talk) 12:45, 18 August 2012 (UTC)


Can someone please check whether the references to "glass transition temperature" in this article should really be "modulus"? Seems like a strange mistake, but my other sources definitely refer to master curves of modulus (of one type or another) vs. time. --Martin2292 (talk) 21:40, 20 February 2009 (UTC)
