Abstract: PURPOSE: A hydrogel is provided to give stimulation reaction by including negative polymers and positive ions and to maintain gel persistence. CONSTITUTION: A hydrogel comprises a hydrophilic or amphipathic polymer including two or more of phosphate(PO4 ^2) groups and polyhydric cation corresponding with negative charged phosphate (PO4^2). The polyhydric cation is selected from low molecular weight compound or polycation including more than 2 cations selected from -NH3 and -N2(CH3)3, and positive charged metal ion having more than bivalent, and combinations thereof. The hydrogel additionally includes 0-20 parts by weight of additive selected from NaCl, CaCl2, NaCSN, PEG and a combination thereof based on 100.0 parts by weight of membranous polymers.
