摘要：
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.COPYRIGHT KIPO 2012본원은 음이온을 가지는 고분자와 양이온을 포함하는 수화젤을 개발하여 젤 지속성이 향상되고 자극반응성을 가지는 수화젤을 제공하고자 한다.
