摘要：
The gel permeation chromatographic properties of poly(vinyl alcohol) gel particles prepared by a freezing-and-thawing procedure were investigated. From the calibration graph established with poly(ethylene glycol) and poly(ethylene oxide) samples, it was found that the value of the excluded molecular mass increased from 2500 (original) to 6000 (fifteen repeated cycles of freezing and thawing). In addition, the treated gels showed a favourable pressure-resisting property.
