(57) [Summary] [Purpose] A silicone polyurethane copolymer containing an oxygen-sensitive phosphorescent dyeing compound. [Constitution] A silicone polyurethane copolymer containing a phosphorescent dyeing compound is provided. The copolymer is represented by the following formula: (Where n is an integer in the range of 1 to about 30, y, z and w are integers in the range of 0 to about 40, y, z And one of w is at least 1; and A represents a diamide group, B represents a silicon block copolymer, and D Represents a chain extender group, and E represents a phosphorescent porphyrin type compound). [Effect] For example, it is useful in a fiber optic element probe used for in vivo measurement of physiological gas. |
