| Research Abstract |
The mean‐square radius of gyration and second virial coefficient were determined from static light scattering measurements for poly(di‐tert‐butyl fumarate) (PDtBF), which is expected to be a precursor of a novel functional gel acting as a superabsorbent polymer, in tetrahydrofuran at 30C. The intrinsic viscosity and hydrodynamic radius were also determined from viscosity and dynamic light scattering measurements, respectively, for PDtBF in the same solvent condition as above. From analyses of the obtained data on the basis of the Kratky‐Porod wormlike chain model, the value of the stiffness parameter for PDtBF was determined. A comparison was made of the results for PDtBF with those for poly(diidopropyl fumarate) (PDiPF) having less bulkier side groups than PDtBF. It was found that the PDtBF chain is much stiffer than the PDiPF one because of the bulky side groups of the former.
