The solubility, dissolution behavior, solution properties, and cellulose recovered from the solutions were investigated. The dissolution took place at room temperature, and the maximum solubility achieved was 16％ (w/w) for cellulose of DP210 in the ethylenediamine/sodium thiocyanate 54/46 (w/w).The dependence of cellulose solubility on DP is also described. Tracing the dissolution behavior of the cellulose by CP/MAS ^<13>CNMR measurements revealed the polymorphic conversion of cellulose l to III to amorphous structure during the dissolution process. The cellulose dissolved was stable for 30 days storage at room temperature. Microscopic observations and steady-shear viscosity measurements of the solutions indicated mesophase formation of cellulose in the ethylenediamine/sodium thiocyanate system. This anisotrpoic phase appeared from ca.10％ (w/w) cellulose with DP210 and greatly depended on the cellulose concentrations. Coagulation studies disclosed that cellulose II and amorphous cellulose were recovered from the cellulose/ethylenediamine/thiocyanate salt solutions when water and alcohol were used as a coagulant, respectively. It was suggested that this solvent system has high potential for cellulosic fiber and film formations.","subitem_description_type":"Abstract"}]},"item_3_description_194":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"44875","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20333669","nameIdentifierScheme":"KAKEN","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000020333669 "}],"names":[{"name":"服部, 和幸","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"44876","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"40166955","nameIdentifierScheme":"KAKEN","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000040166955 "}],"names":[{"name":"吉田, 孝","nameLang":"ja"}]}]},"item_3_publisher_212":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人 高分子学会"}]},"item_3_relation_191":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://doi.org/10.1295/polymj.36.123","subitem_relation_type_select":"DOI"}}]},"item_3_rights_192":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Society of Polymer Science, Japan, Kazuyuki Hattori, Emiko Abe, Takashi Yoshida and John A.
