摘要:
The utilization of sorption and diffusion phenomena of low molecular weight polymer swelling penetrants has been shown in the present work to make it possible to detect morphological differences in unmodified samples of polycarbonates. A suitable active penetrant has been found to bring out differences in the mobilities of areas with varying degrees of molecular ordering. These differences can then be measured by NMR.
