    • note
    • Samples for DSC analyses were prepared as follows: A mixture (0.10 g) of poly(HMPA) 1 with commodity polymer at a desired ratio was dissolved in small amount of chloroform. The solution was then reprecipitated into large amount of n-hexane to give a pale yellow solid. After filtration and freeze-drying of the mixture, the resulting solid was dried in vacuo and the sample was obtained as a pale yellow powder or gum.
