Zeeshan sent me some samples to run on the DSC. These include waxes and several polymers.
The following include sample names, pan masses, sample masses, and DSC sample numbers. Aluminum Tzero pans from TA instruments were used. No caps or seals were used.
Note: The mass of the 135 wax might be a little low. the balance was doing something funny. Check this later.
DSC run parameters
The results shown below highlight the observed melting points. Note: Melting points were only observed in the first heating scans for each sample. They were not reversible. Also, for the PNI PAm variants, glass transitions were observed at higher temperatures (130-160) but are not listed/shown here. In the graphs below, the number in parentheses is the measured melting point, determined from the derivative graph [d(mW)/dT], which aren't shown here.
The thymine sample didn't show very much change at all.
