      abstract     = {Syndiotactic polystyrene (sPS) is a crystalline polymer
                      which has a unique property; it is able to form cocrystals
                      with a wide range of chemical compounds, in which the guest
                      molecules are confined in the vacancies of the host sPS
                      crystalline region. Recently, it has been found that even
                      polyethylene glycol oligomers with a molecular weight of
                      more than several hundreds can be introduced into the sPS
                      crystalline region. It is quite important to know how such a
                      long-chain molecule is stored in the host sPS lattice. To
                      tackle this issue, a new simultaneous measurement method
                      combing small-angle neutron scattering and Fourier transform
                      infrared spectroscopy (SANS/FTIR), which has been recently
                      developed by the authors, was applied to an sPS cocrystal
                      with polyethylene glycol dimethyl ether with a molecular
                      weight of 500 (PEGDME500). The temperature-dependent changes
                      of the SANS profile and FTIR spectrum were followed from
                      room temperature up to 413 K for a one-dimensionally
                      oriented SANS/PEGDME500 cocrystal sample. The intensity of
                      the reflections due to the stacking of crystalline lamellae
                      showed a significant temperature dependence. The
                      two-dimensional pattern in the high Q region of SANS also
                      changed depending on temperature. The combined information
                      obtained by SANS and FTIR suggested that PEGDME500 molecules
                      are distributed in both the crystalline and amorphous
                      regions in the low-temperature region close to room
                      temperature, but they are predominantly included in the
                      amorphous region in the high-temperature region. It was also
                      suggested by the two-dimensional SANS profile that PEGDME500
                      molecules in the crystalline region have an elongated
                      structure along the thickness direction of the crystalline
                      lamellae.},
