NMR IMAGING OF ACETONE DIFFUSION PROCESS IN POLYCARBONATE

Received Date: 29 April 1992

Acetone diffusion in polycarbonate was investigated by spin-echo 1H NMR imaging method at room temperature. The result shows that the diffusion process satisfies Case Ⅱ diffusion. The velocity of diffusion front is 13.8nm sec-1(0.05mm/h).
