Abstract

Spatial inhomogeneities of slide-ring (SR) gel under uniaxial stretching were observed by small angle neutron scattering. SR gels were prepared in 1N NaOD aqueous solution (NaOD). The scattering intensity of SR gel decreased with increasing the cross-link concentration. These results agree with the result of the SR gel in DMSO system. The network of SR gel was homogeneous because of repulsive interaction between dissociated hydroxyl groups on α-cyclodextrin molecule in NaODaq. The 2D scattering pattern under uniaxial stretching showed a normal butterfly pattern in which the intensity increased perpendicularly to the stretching direction. In contrast, the conventional chemical gel showed an abnormal butterfly pattern in which the intensity increased parallel to the stretching direction. Since the cross-links of SR gels can move freely along the polymer chains, an increase of spatial inhomogeneities was suppressed.
