摘要：

The swelling behavior of chemically crosslinked poly(vinylalcohol) is studied in borax solution in presence or without added salt. In borax solution, the gel, initially neutral beads swells because anionic charges appear on the chain by complexation, the swelling depends on the mesh size. When NaCl is added, the charges on the polymeric chains are screened and the gel will contract. © 1990 Springer-Verlag.
