Aromatic dialdehyde-based bisbenzoxazines: The influence of relative position of oxazine rings

Abstract

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Metal Complexes of the Porphyrin-Functionalized Polybenzoxazine

“…Because strong inter- and intramolecular hydrogen bonds exist after the thermal ROP of BZ units, formed among the tertiary amino and phenolic units in the Mannich bridges, the polymerization products can possess low dielectric constants, low surface free energies, low degrees of shrinkage, and high thermal stabilities and char yields [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Flexibility in molecular design—by varying the structures of the phenolic and amino groups—has allowed the introduction of a range of functional groups (e.g., allyl, propargyl, crown ether) [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ] or inorganic nanomaterials (such as polyhedral oligomeric silsesquioxane, graphene, carbon nanotube) [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ] into the BZ matrix.…”

Catechin and Furfurylamine Derived Biobased Benzoxazine with Latent‐Catalyst Effect

“…It is considered a viable approach to affect the ROP temperature and tailor the polymer properties. [ 17–22 ]…”

“…It is considered a viable approach to affect the ROP temperature and tailor the polymer properties. [17][18][19][20][21][22] The natural abundance of biomass is attractive and offers a wide resource of renewable feedstock to supplement the requirement for sustainable polymers. Furthermore, the presence of inherent functionalities in these naturally occurring molecules enact them as a desirable molecular scaffold, which is otherwise difficult to synthesize from petro-sourced chemicals.…”

Polybenzoxazines: a sustainable platform for the design of fast responsive and catalyst-free vitrimers based on trans-esterification exchanges

“…44 However, to solve the concern of its carcinogenetic, its substitution by more friendly aldehydes has been under the spotlight of very significant investigations. 45,46 It makes no doubts that polybenzoxazines with an excellent life cycle impact will emerge in the coming years.…”
