えると流動性が増し、弾性も低下する。(Effects of the Invention) In the elastic composition of the present invention, water and/or water-soluble alcohol molecules are bonded to a matrix formed by the hydrophilic polymer compound of component (A) and the oxide glass of component (B), Alternatively, it is believed that it is contained in a molecularly dispersed form between the matrix. Therefore, the presence of water and/or water-soluble alcohol appears to contribute significantly to the elasticity of the treated composition. In fact, the elasticity decreases as the water and/or water-soluble alcohol content decreases. Further, as the content of water and/or water-soluble alcohol increases, the elasticity increases, but when it exceeds a certain value of 1, the fluidity increases and the elasticity decreases.

It is more expensive than inorganic materials, and its uses are greatly expanded. For example, it can be used as a core material for golf balls. On the other hand, materials with high fluidity and low elasticity can be used for toys that can change shape.
