The system and technique are those described above . To determine the ester
interchange reaction rate , the authors annealed the films at 200 and 225°C .
Table 4 shows the duration of annealing and how many DEG units were
transferred .

But after annealing at temperatures below the glass transition an endothermic
peak develops as temperature is scanned through the glass transition [ 70 , 71 ) .
The height of this peak increases with the duration of the sub - T , annealing .
