Abstract
The polymer gel obtained from the method for incorporating hydroxyapatite in a polymer hydrogel by impregnating an aqueous phosphoric acid alkali metal salt solution and an aqueous carbonate solution alternately one or more times with a polymer gel consisting of a polymer of a water-soluble organic monomer and a water-swelling clay mineral, contains finely dispersed biocompatible substances, and the polymer gel excels in dynamic physical property and stability and can exhibit the performance of the biocompatible substance efficiently. The dried biocompatible substance-containing polymer gel is obtained by drying the above polymer gel.
Claims21
A polymer gel comprising a three-dimensional network formed by complexing a polymer of a water-soluble organic monomer with a water-swelling clay material, wherein the three-dimensional network contains a biopolymer or an inorganic substance having biocompatibility therein.
A process for producing a polymer gel, comprising:
- polymerizing a water-soluble organic monomer in a uniform solution which contains the water-soluble organic monomer, a water-swelling clay mineral, a biocompatible substance and water.
A process for producing a polymer gel, comprising:
- forming hydorxyapatite in a polymer hydrogel by impregnating an aqueous soultion of a phosphoric acid alkali metal salt and an aqueous solution of carbonate alternately one or more times with a polymer gel consisting of a water-soluble organic monomer and a water-swelling clay mineral.
