Epoxy resins were synthesized from the above prepolymers by reaction with poly(azelaic anhydride). The molar ratios of acid anhydride groups to epoxy groups ([AA/EPOXY] ratios) were varied at 10/10 and 12/10. The thermal properties of the obtained prepolymers and epoxy resins were studied by differential scanning calorimetry (DSC), thermogravimetry (TG) and TG- Fourier transform infrared spectroscopy (FTIR). The values at glass transition temperatures (T_g's) of epoxy resins decreased in the order of epoxy resins from HQ > AL > MHQ. Thermal degradation temperatures (T_d's) of epoxy resins were a]most constant regardless of [AA/EPOXY] ratios, suggesting that the curing of prepolymers with poly(azelaic anhydride) does not affect T_d values. The intensities of absorption peaks at 2900 cm-1 (CH) and 1730 cm-1 (C=0) in IR spectra of the evolved gases during thermal degradation increased with increasing [AA/EPOXY] ratios.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00000429","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00008888","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2868571","subitem_source_identifier_type":"ISSN"}]},"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":"Hirose, Shigeo"}],"nameIdentifiers":[{"nameIdentifier":"9952","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatakeyama, Hyoe"}],"nameIdentifiers":[{"nameIdentifier":"9953","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-04-12"}],"displaytype":"detail","filename":"KJ00000201973.pdf","filesize":[{"value":"363.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000201973.pdf","url":"https://fut.repo.nii.ac.jp/record/435/files/KJ00000201973.pdf"},"version_id":"838a104f-1baf-45dc-8945-d5e1fb0c76bd"}]},"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":"Thermal Properties of Epoxy Resins from Lignin and Lignin-related Phenols","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thermal Properties of Epoxy Resins from Lignin and Lignin-related Phenols"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-04"},"publish_date":"2009-04-04","publish_status":"0","recid":"435","relation_version_is_last":true,"title":["Thermal Properties of Epoxy Resins from Lignin and Lignin-related Phenols"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:32:34.329579+00:00"}
