The PUEs were synthesized from PC-glycol, 4,4’-diphenylmethane diisocyanate and 1,4-butandiol by a one-shot method. The degree of microphase separation became weaker with an increase in the BEPG content. This trend results in a decrease in Young’s modulus due to the lack of the formation of crystallized hard segment domains in the PUEs. Tensile strength and strain at break decreased and increased with increasing BEPG content, respectively. This result clearly suggests that butyl and ethyl groups of the BEPG molecule suppressed the packing of the soft segment under elongation.","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, Vol.40(75), pp.29-33 ; 2010","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"57074","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kojio, Ken"}]},{"nameIdentifiers":[{"nameIdentifier":"57075","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Furukawa, Mutsuhisa"}]},{"nameIdentifiers":[{"nameIdentifier":"57076","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Motokucho, Suguru"}]},{"nameIdentifiers":[{"nameIdentifier":"57077","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Mizokami, Motonori"}]}]},"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":"AA12080680","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-5574","subitem_source_identifier_type":"ISSN"}]},"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":"小椎尾, 謙"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古川, 睦久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"本九町, 卓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"溝上, 元規"}],"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":"40_75_05.pdf","filesize":[{"value":"3.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"40_75_05.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/15407/files/40_75_05.pdf"},"version_id":"27c68bf3-e972-41fe-a943-66baa72d004e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"polycarbonate glycol","subitem_subject_scheme":"Other"},{"subitem_subject":"side groups","subitem_subject_scheme":"Other"},{"subitem_subject":"aggregation structure","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical properties","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"種々の側鎖メチル基含有率を有する共重合ポリカーボネートを基材としたポリウレタンの凝集構造と力学物性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"種々の側鎖メチル基含有率を有する共重合ポリカーボネートを基材としたポリウレタンの凝集構造と力学物性"}]},"item_type_id":"3","owner":"2","path":["1241"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-07-07"},"publish_date":"2010-07-07","publish_status":"0","recid":"15407","relation_version_is_last":true,"title":["種々の側鎖メチル基含有率を有する共重合ポリカーボネートを基材としたポリウレタンの凝集構造と力学物性"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-17T21:17:47.700408+00:00"}
