Abstract
The swelling behavior of PET (polyethylene terepthalate) film immersed in insulating liquid was investigated, and the swelling kinetics of the PET was evaluated. It was found that the swelling behavior can be measured more effectively by a weight measurement than by a thickness measurement. The swelling process was found to be proportional to the square root of time. The swelling of the PET caused a change in the glass transition temperature, which can be explained by Fox´s equation
