Biomaterials formed by nucleophilic addition reaction to conjugated unsaturated groups

[Subject] Offer of the synthetic biocompatible material containing polymerization hydrogel. [Means for Solution] A stage of combining a precursive constituent beyond two or it of the biocompatible material under conditions which are a method for producing a biocompatible material and whose polymerization of two constituents is attained is included, The polymerization arises by the self-alternative reaction between a strong nucleophilic reagent, a conjugate unsaturated bond, or a conjugate unsaturated machine by 求核 addition, A way a functional value (functionality) of a class product is at least 2, and the conjugate unsaturated bond or a conjugate unsaturated machine is not maleimide or vinyl SURUHON excluding (unprocessed) albumin by which the biocompatible material is not processed.
