WebIn this temperature range the heat capacity is largely independent of the physical structure. Glass and crystal have almost the same heat capacity. This is followed, again, by a steeper increase in heat capacity as the amorphous polymer undergoes its glass transition at about 230-250 K. The bottom lines in the right graph of Fig.1 show the WebAbove the Tg, the rubbery, flexible polymer has a higher heat capacity. For some thermoset polymers, the Tg can be below 25°C in which case the polymer will be a soft, flexible polymer at 25°C. This is typically true with silicones as well as with flexible epoxies or urethanes. They cure with a long flexible chain that does not require much ...
