Comparison of porosity characteristics of macroporous poly(styrene–divinylbenzene) resins determined from mercury intrusion data and image analysis of transmission electron micrographs
Abstract
The porosity characteristics of a series of 12 macroporous poly(styrene–divinylbenzene) resins have been quantified by the mercury intrusion method and by image analysis of transmission electron micrographs (TEM) of resin particle cross-sections. The results from both methods correlate extremely well. Bearing in mind that the TEM procedure does ‘observe’ pores more directly than the Hg intrusion method, the present study tends to validate the intrusion procedure and calculations.
