The copolymerized gel of PDMS-\u003ci\u003eco\u003c/i\u003e-PDMAA had bicontinuous phase separated domains (hydrophilic and hydrophobic) with periodicity in nano meter scale. In present work, the structure of the gels in three different conditions (1: dry state, 2: swollen in water, 3: swollen in water/methanol mixed solvent) was analyzed by SAXS. The hydrophilic region was confirmed to be swollen selectively by water and methanol. The electron density of hydrophilic region varied according to the mixture ratio and adsorption amount of the solvents, although the phase separated structure also changed by swelling. The experimental scattering intensity was compared with theoretical one calculated by multiplying square of the electron density difference and volume fraction of each domain. In dry state and in swollen state with water, the scattering intensity was interpreted by two phases. In contrast, the methanol content dependence of the SAXS intensity of the gels in does not agree with the model composing the two regions but fits quite well with three-region model in water/methanol mixed solvent. The solvent poor region near the interface between the phase separated domains was disclosed when the electron density of hydrophilic domains was close to that of hydrophobic (PDMS) domains.",

The copolymerized gel of PDMS-<i>co</i>-PDMAA had bicontinuous phase separated domains (hydrophilic and hydrophobic) with periodicity in nano meter scale. In present work, the structure of the gels in three different conditions (1: dry state, 2: swollen in water, 3: swollen in water/methanol mixed solvent) was analyzed by SAXS. The hydrophilic region was confirmed to be swollen selectively by water and methanol. The electron density of hydrophilic region varied according to the mixture ratio and adsorption amount of the solvents, although the phase separated structure also changed by swelling. The experimental scattering intensity was compared with theoretical one calculated by multiplying square of the electron density difference and volume fraction of each domain.
