DESWELLING BEHAVIOR OF POLY(TETRAETHYLENEPENTAMINE EPICHLOROHYDRIN)GELS HYDROPHOBICALLY MODIFIED BY STEARIC ACID

Received Date: 17 May 1998

A novel type of polysoap hydrogel based on poly(tetraethylenepentamine-epichlorohydrin)hydrophobically modified by stearic acid was prepared. The deswelling behaviors of polysoap hydrogels werestudied by immersing the gels in buffer solution at various pHs and ionic species. The deswelling of the gelsdid not depend on the cationic species of electrolyte but depended strongly on the anionic species. Acomparison of polysoap gels with the gel unmodified hydrophobically verified the importance of hydrophobic interaction,which enhances the occurrence of deswelling rate.
