A relationship between conformational disordering and rotational motion of molecular chains was detected by comparing two types of data. The structural change in the photoinduced solid-state polymerization of cis,cis-diethylmuconate single crystals was also studied. It was found that the molecular deformation of the polymer chains and lattice strain was induced in the early stage of polymerization reaction.Mahidol UniversityChemistryMaterials SciencePhysics and AstronomyDevelopment of a simultaneous measurement system of X-ray diffraction and Raman spectra: Application to structural study of crystalline-phase transitions of chain moleculesArticleSCOPUS10.1002/polb.10112
