Highly softened TEGDI-based PUEs were successfully prepared on account of flexibility of TEGDI itself and weaker phase separation. A relationship between conformation and molecular mobility of the soft segment were investigated using dynamic viscoelastic measurement. The peaks of α relaxation of the soft segment chains were clearly observed in the loss tangent (tan δ) curves at various strains. The onset temperature of α relaxation decreased with increasing strain. This result indicates that the size of cooperative motion of the glass transition decreased due to the orientation of the soft segment chains with increasing strain. The effect of the microaggregation structure on the rheological properties of thermoplastic polyurethane (TPU) were investigated. The TPUs showed the strain hardening of uniaxial elongation viscosity with increasing annealing temperature owing to residual hard segment domains at an operating temperature. It was revealed that the formation of well-organized hard segment domains had a profound effect on the rheological properties of TPUs, in particular on their elongational viscosity.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"日本レオロジー学会誌, 36(5), pp.229-234; 2008","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"64777","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kojio, Ken"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本レオロジー学会"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1678/rheology.36.229","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2008 The Society of Rheology, Japan."}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00198812","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03871533","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"The Society of Rheology,Japan"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小椎尾, 謙"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-23"}],"displaytype":"detail","filename":"NRG36_229.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NRG36_229.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/16767/files/NRG36_229.pdf"},"version_id":"8217d006-239c-4d8f-83ec-eefb12167478"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Elongation","subitem_subject_scheme":"Other"},{"subitem_subject":"Microphase-separated structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Molecular mobility","subitem_subject_scheme":"Other"},{"subitem_subject":"Polyurethanes","subitem_subject_scheme":"Other"},{"subitem_subject":"Uniaxial elongational viscosity","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ポリウレタンのミクロ相分離構造とレオロジー特性に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポリウレタンのミクロ相分離構造とレオロジー特性に関する研究"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-18"},"publish_date":"2009-12-18","publish_status":"0","recid":"16767","relation_version_is_last":true,"title":["ポリウレタンのミクロ相分離構造とレオロジー特性に関する研究"],"weko_creator_id":"2","weko_shared_id":2},"updated":"2023-05-15T19:11:28.071991+00:00"}
