摘要：
The effect of long range electrostic interactions on gelation of polyelectrolyte chains induced by multivalent ions was determined. The approach taken could be used to describe gelation of charged chains bridged by other types of linkers through modification of K2. It was also possible to account for variable weights of different types of cross-link functionalities m by allowing a Km dependence.
