Differential scanning calorimetry and wide-angle X-ray diffraction analyses revealed that PEOxz-PTHF-PEOxzs produced a microphase separation structure, which consisted of a partially crystallized amorphous PTHF phase containing PEOxz chains on both ends. Tensile testing showed that PEOxz-PTHF-PEOxz exhibited tough mechanical properties that differed from those of the brittle PTHF homopolymer. Thus, it was suggested that the amorphous PTHF/PEOxz phase played a role in physically cross-linking the moieties via entanglement, resulting in a PEOxz-PTHF-PEOxz material with tough mechanical properties and the ability to be cold-drawn.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Polymer Journal, 45(11), pp.1115-1119; 2013","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Society of Polymer Science, Japan"}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/pj.2013.39","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2013 The Society of Polymer Science, Japan (SPSJ)"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00323896","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"13490540","subitem_source_identifier_type":"ISSN"}]},"item_2_text_62":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"高分子学会"}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Motokucho, Suguru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furukawa, Mutsuhisa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawashima, Masahiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kojio, Ken"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshinaga, Kohji"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-18"}],"displaytype":"detail","filename":"PJ45_1115.pdf","filesize":[{"value":"622.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PJ45_1115.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/1012/files/PJ45_1115.pdf"},"version_id":"6c2e15da-d75a-471f-ba76-b9fc4368cc02"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"block copolymer","subitem_subject_scheme":"Other"},{"subitem_subject":"phase separation","subitem_subject_scheme":"Other"},{"subitem_subject":"poly(tetrahydrofuran)","subitem_subject_scheme":"Other"},{"subitem_subject":"ring-opening polymerization","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Physical properties of poly(tetrahydrofuran)-block-poly(2-ethyl-2-oxazoline) triblock copolymer","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Physical properties of poly(tetrahydrofuran)-block-poly(2-ethyl-2-oxazoline) triblock copolymer"}]},"item_type_id":"2","owner":"2","path":["21"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-08-24"},"publish_date":"2020-08-24","publish_status":"0","recid":"1012","relation_version_is_last":true,"title":["Physical properties of poly(tetrahydrofuran)-block-poly(2-ethyl-2-oxazoline) triblock copolymer"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T04:09:15.460614+00:00"}
