In order to demonstrate the superiority of the new synthetic procedure, five kinds of GTPs were synthesized with different types of alkyne derivatives. GAP was synthesized through the reaction between polyepichlorohydrin and sodium azide in N,N-dimethylformamide. For handling impact- and friction- sensitive solid GAP safely, it was purified through liquid–liquid extraction and stored as a stock solution without isolating it in the solid state. Through the new procedure utilizing a stock solution, the reaction efficiency in GTP synthesis was greatly improved, which resulted in reducing material loss (Feed ratio alkyne/azide: from 4.0 to 1.3) and reaction time (from 72 to 24 h). Thanks to the facile, efficient, and safe synthetic method, enough amounts of GTP samples could be prepared for characterizing not only physicochemical properties (density, molecular weight, glass transition temperature, thermal decomposition temperature, surface free energy) but also mechanical properties (Young's modulus, fracture stress and strain). The synthetic procedure reported herein will accelerate the research and development of functional GTPs with tunable physical properties." description_type: abstract lang: und ## Creator - name: Taichi Ikeda role: author orcid: https://orcid.org/0000-0001-6650-5798 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 - name: Naoe Hosoda role: author orcid: https://orcid.org/0000-0002-7440-4927 organization: National Institute for Materials Science ror: https://ror.org/026v1ze26 ## Contact agent ## Publisher organization: Wiley ## Managing organization ## Keyword - subject: azide- alkyne cycloaddition schema: not_defined - subject: click chemistry schema: not_defined - subject: glycidyl triazolyl polymers schema: not_defined - subject: polyethers schema: not_defined - subject: post- functionalization of polymers schema: not_defined ## Rights - identifier: https://creativecommons.org/licenses/by/4.0/ ## Other identifier(s) ## Data origin - data_origin_type: other ## Embargo ## Journal - title: Journal of Polymer Science issn: '26424150' volume: '63' issue: '12' start_page: 2568 end_page: 2578 ## Conference ## Related item ## Funding - identifier: '24126704' funder_name: Cabinet Office, Government of Japan - identifier: 22K05246 funder_name: Japan Society for the Promotion of Science ## Instrument ## Instrument operator ## Instrument managing organization ## Measurement method ## Specimen ## Chemical composition ## Structure for specimen ## Structural feature for specimen ## Specific property for specimen ## Process for specimen treatment ## Computational method ## Energy level/transition state ## Software ## Custom property ## Fileset - id: d71fa0fe-ef63-4a94-8356-0d72b8acc0b0 filename: 2025-JPolymSci.pdf content_type: application/pdf size: 1428894 md5: 0a7e2ecc4fce67090e195763846570d6 - id: 96ab02a6-048b-4fae-b132-cfb67754d911 filename: 2025-JPolymSci-SI.pdf content_type: application/pdf size: 3519277 md5: 976cb3144fa1917d942e92e6f1b14145 - id: a29670b8-8408-44ea-ae8f-e3ab7712af08 filename: Data_Figure_4_SEC.txt content_type: text/plain size: 50243 md5: 840d10f80474aa27c7827c93a5965f3d - id: ad25199a-f69b-4827-a42b-8d96c7ff3122 filename: Data_Figure_6_SS_curve.txt content_type: text/plain size: 319486 md5: b53e121022a009eecdf8c04dc29ada26 - id: 6d7f2810-a9e4-4039-90ff-d7855ddd34c1 filename: Data_Figure_S14_IR.txt content_type: text/plain size: 181046 md5: 0d402dc28c215e40d543b75042d9bcb9 - id: 0436214e-efcd-49c3-bb09-3f99f230cc02 filename: Data_Figure_S15_DSC.txt content_type: text/plain size: 159777 md5: d8e058c54a7545115b271fb21a3bbd6b - id: 470b98f2-efa6-4cf9-b4e4-83dcaa336a5b filename: Data_Figure_S16_DSC.txt content_type: text/plain size: 26094 md5: 7e93e1d3c4033b122975c2646e43f308 - id: 457c9b52-8e98-4c7b-9ac8-952ae44d4d8d filename: Data_Figure_S17_TGA.txt content_type: text/plain size: 42832 md5: 6d48cec7859355f5ff16f7c2016ae8d2 - id: f8260419-9cac-40e7-aa46-325ac14b3b23 filename: Data_Figure_S18_SS_curve.txt content_type: text/plain size: 302380 md5: 5af581bf7221e6f8bf4c54ff058ec42b ## Thumbnail fileset_id: d71fa0fe-ef63-4a94-8356-0d72b8acc0b0 filename: 2025-JPolymSci.pdf
