Uniaxially stretched gels

The eKperimental situation can be summarised as follows Crosslinked and swollen polystyrene gels exhibit a chain deformation which is less than that given by all phantom network models Early experiments by Clough et al, on radiation crosslinked polystyrene networks had been interpreted to be consistent with the free-fluctuation phantom scattering law. Most of the scattering experiments which were performed on uniaxially stretched end-linked siloxane networks showed much smaller molecular deformations than would be predicted even from Eq. (78) To...
