Properties and Curing Kinetics of a Processable Binary Benzoxazine Blend

Abstract
High Resolution Image Download MS PowerPoint Slide A benzoxazine system is presented combining liquid cardanol-based benzoxazine (CA-a) and an effective initiator (3,3′-thiodipropionic acid, TDA) to bisphenol A-based benzoxazine (BA-a). The resultant mixture of monomeric precursors shows excellent fluidity and a relatively low peak polymerization temperature of around 200 °C. Moreover, the cured polybenzoxazine displays a high thermal decomposition temperature ( T d,5% > 330 °C), a moderately high glass transition temperature (∼148 °C), and robust mechanical strength (storage modulus ∼ 2.8 GPa) comparable to those of the polybenzoxazine homopolymer obtained by curing BA-a. A comprehensive investigation into the microstructure and curing kinetics has also been conducted on the system, offering an extensive background for future studies.
