The dynamic viscoelastic properties of the segmented polyurethanes were studied in a wide range of temperature. These segmented polyurethanes were prepared by prepolymer technique using polyoxy tetramethylene glycol (PTMG) (Mn=1000 and 2000) and 4, 4'-diphenylmethanediisocyanate as starting materials and hydrazine and ethylenediamine as chain extenders. The samples were studied at a frequency of 110 Hz by Vibron DDV III-B. Differential scanning calorimetry (DSC) and infrared spectroscopy were also studied. These segmented polyurethanes showed tanδ maxima at two temperatures (-120℃ and -50℃). As the hard segment concentration was increased, main dispersion shifted to a lower temperature, its height of tanδ peak decreased and its width widened. As the moleculare weight of PTMG was increased, main dispersion shifted to a lower temperature. Storage modulus E' in a series of PTMG 1000-HD was increased as hard segment concentration was increased, but E' in a series of PTMG 2000-HD and -EDA were not affected. The dispersions were interpreted in terms of molecular motion and the difference of composition of segmented polyurethanes.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告, (5), pp.135-142; 1974","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"59302","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Furukawa, Mutsuhisa"}]},{"nameIdentifiers":[{"nameIdentifier":"59303","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ogata, Motonori"}]},{"nameIdentifiers":[{"nameIdentifier":"59304","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yokoyama, Tetsuo"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178418","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02860902","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"18805574","subitem_source_identifier_type":"ISSN"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Nagasaki University"}]},"item_3_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":"古川, 睦久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"緒方, 元範"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"横山, 哲夫"}],"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":"kogaku00_05_17.pdf","filesize":[{"value":"529.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kogaku00_05_17.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/15871/files/kogaku00_05_17.pdf"},"version_id":"5eaba3be-875e-49f8-aabf-f399aaa97e0e"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"セグメンティドポリウレタンの動的粘弾性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"セグメンティドポリウレタンの動的粘弾性"}]},"item_type_id":"3","owner":"2","path":["1262"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-09-07"},"publish_date":"2010-09-07","publish_status":"0","recid":"15871","relation_version_is_last":true,"title":["セグメンティドポリウレタンの動的粘弾性"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T21:07:33.847208+00:00"}
