Benzoxazine blend

In this study, two benzoxazine monomers, m-alkylphenyl-3,4-dihydro-2Hbenzoxazine (CA-Bz) and 4,4 Ꞌ -Bis-[6-(3-phenyl-3,4-dihydro-2H-1, 3-benzoxazine)] pentanoic acid (DPA-Bz) were successfully synthesized from fully bio-based phenols (cardanol and diphenolic acid). Their structures were confirmed by FTIR and NMR spectroscopy. CABz/DPA-Bz blend was prepared at weight ratio of 3:1. Polymerization behavior of the blend was investigated by DSC.
