| Abstract: | A systematic study of supercritical carbon dioxide swelling six different polymers,namely,LDPE,PP,PA6,EVA,PS,PU,was investigated.When critical factors such as temperature,pressure and time of the SC-CO 2 treatment,and dimension of samples were changed,changes in appearance and weight had been observed.The weight change of polymers after treatment in mass with time showed a linear dependence on the logarithm of time. |

| Keywords: | supercritical carbon dioxide swelling exposure temperature exposure pressure exposure time decompression time desorption curve |
