Subsequent thermal cyclodehydration of the precursor polymer at 300°C successfully afforded the polybenzoxazole with high molecular weight. The poly(o-hydroxy amide) dissolved in polar aprotic solvents, whereas the polybenzoxazole was insoluble in any organic medium tested. The polybenzoxazole was stable up to around 400°C under nitrogen and had a low dielectric constant of 2.866. The mechanical properties of the polybenzoxazole film were excellent, its tensile strength, elongation at break, and tensile modulus were 110 MPa, 6%, and 3.3 GPa, respectively.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34411/00001028","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川工科大学"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10074179","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09161902","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"三枝, 靖夫","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"高澤, 秀生","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"森川, 浩","creatorNameLang":"ja"}]},{"creatorNames":[{"creatorName":"Saegusa, Yasuo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Takazawa, Hideo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Morikawa, Hiroshi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-02-28"}],"displaytype":"detail","filename":"kkb-033-005.pdf","filesize":[{"value":"705.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kkb-033-005.pdf","objectType":"fulltext","url":"https://kait.repo.nii.ac.jp/record/1035/files/kkb-033-005.pdf"},"version_id":"2fc05950-9474-49e9-a294-6af473efe8ed"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Dimethyladamantyl unit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"semi-alicyclic polybenzoxazole","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"silylation method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"high thermal stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"low dielectric constant","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Synthesis and Characterization of Dimethyladamantyl Unit-Containing Semi-Alicyclic Polybenzoxazole","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Synthesis and Characterization of Dimethyladamantyl Unit-Containing Semi-Alicyclic Polybenzoxazole","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"4","path":["123"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-11-24"},"publish_date":"2020-11-24","publish_status":"0","recid":"1035","relation_version_is_last":true,"title":["Synthesis and Characterization of Dimethyladamantyl Unit-Containing Semi-Alicyclic Polybenzoxazole"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-04T09:17:39.098552+00:00"}
