Plant‐Derived Polyphenols for Sustainable Flame‐Retardant Coatings

open access: yesChemistry–Methods, Volume 6, Issue 1, January 2026.
This review compares plant‐derived polyphenolic flame retardants by synthesizing literature on their mechanisms, synergistic effects, and performance across polymers, wood, fibers, and coatings, while examining biodegradability, life cycle assessment, safe‐and‐sustainable‐by‐design, and consistency with circular‐economy principles for sustainable fire ...

Fluorinated benzoxazines and the structure-property relationship of resulting polybenzoxazines

open access: yes, 2014
Three fluorinated benzoxazines (14-16), which cannot be synthesized by the traditional one-step approaches, were synthesized by a three-step procedure using fluorinated aromatic diamines (2-4) as starting materials.

Solvent-free synthesis of novel mono- and bis-benzoxazines from cashew nut shell liquid components

open access: yes, 2012
Cashew nut shell liquid (CNSL) is a largely available by-product of the cashew agro-industry. In this paper, the main constituents (cardanol, cardol and methylcardol) obtained after separation of the CNSL mixture have been used as starting material to ...

Studies on Benzoxazine Derivaties

open access: yesInternational Journal for Research in Applied Science and Engineering Technology
Abstract: The 5, 6, 7 trimethoxy (1, 4) benzoxazine -2,3diones was synthesized by reaction of 2-amino-3,4,5 trimethoxyphenol with oxalyl chloride. The new compound of benzoxazine derivative was characterized by elemental analysis, mass spectroscopy , infrared and 1H-NMR . The compound exhibited antifungal and antibacterial activities.
