  • ULTRA-HIGH STRENGTH INJECTABLE HYDROGEL AND PROCESS FOR PRODUCING THE SAME
    Publication number: 20120122949
    Abstract: [Problem] The present invention is intended to provide high-strength hydrogels and method for fabricating the same. The present invention is intended to provide the method for fabricating the hydrogels with different decomposition rates. [Solution to Problem] The present invention is based on a knowledge that high-strength hydrogels can be fabricated by controlling pH of solution, ionic strength in the solution, and buffer concentration in the solution. In addition, the present invention is based on a knowledge that the high-strength hydrogels which have homogeneous macromolecular network structure can be fabricated by polymerizing four-branching compounds after having dispersed the four-branching compounds homogeneously.
