A simple route for the synthesis of a thermally conductive polybenzoxazine containing liquid crystalline (LC) structure by grafting oligomeric <jats:italic>p<\/jats:italic>\u2010sulfophenylene\u2010terephthalamide (PSTA) is offered. Benzoxazine monomer of <jats:italic>p<\/jats:italic>HBA\u2010da is synthesized via Mannich reaction of <jats:italic>p<\/jats:italic>\u2010hydroxy benzoic acid, <jats:italic>p<\/jats:italic>\u2010formaldehyde, and dodecyl amine. After ring\u2010opening polymerization, the oligomer benzoxazine of OBZ\u2500COOH is obtained. The OBZ\u2500COOH\/PSTA mixture is prepared by mixing PSTA with OBZ\u2500COOH. Afterward, the grafted copolymer is named OBZ\u2500PSTA copolymer. The liquid crystalline behavior of OBZ\u2500COOH\/PSTA is studied by polarized optical microscopy and small angle X\u2010ray scattering analysis. The results show that the OBZ\u2500PSTA forms the LC structure during isothermal and non\u2010isothermal curing. The LC structure displays a floral textured nematic phase. The phase formation is induced by an amidation reaction. Due to the grafts of LC PSTA, the thermal conductivity of OBZ\u2500PSTA is 0.296\u00a0W m<jats:sup>\u22121<\/jats:sup> K<jats:sup>\u22121<\/jats:sup>, which is 26% greater than OBZ\u2500COOH. The glass transition temperature (<jats:italic>T<\/jats:italic><jats:sub>g<\/jats:sub>) of OBZ\u2500PSTA is 241\u00a0\u00b0C. The 5% (<jats:italic>T<\/jats:italic><jats:sub>d5<\/jats:sub>) and 10% weight loss temperatures (<jats:italic>T<\/jats:italic><jats:sub>d10<\/jats:sub>) of OBZ\u2500PSTA are 346 and 362\u00a0\u00b0C, respectively.<\/jats:p>","DOI":"10.1002\/smll.202306031","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T03:11:11Z","timestamp":1696561871000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Reaction\u2010Induced Liquid Crystalline Polybenzoxazine Bearing\u00a0Aromatic Amide Side Branches"],"prefix":"10.1002","volume":"20","author":[{"given":"Irum","family":"Rafique","sequence":"first","affiliation":[{"name":"Key Laboratory for Special Functional Aggregated Materials of Ministry of Education School of Chemistry and Chemical Engineering Shandong University  Jinan 250100 P.
