MEG and PMEG were synthesized to modify BMI resins, and the cured MEG-BMI resins showed good thermal stability and high carbon content. As a new candidate high temperature thermosetting resin, MEG has promising applications in advanced composite matrices.
Hydroxymethylated eugenol (MEG) and poly (hydroxymethylated eugenol) (PMEG) were synthesized by the condensation reaction of eugenol (EG) with formaldehyde. The different contents of MEG and PMEG were used to modify 4,4 '-bismaleimidediphenylmethane (BMI). The cured MEG-BMI resins exhibit good thermal stability evidenced by its 5% weight loss temperatures above 407 degrees C and its residue above 39.4% at 800 degrees C under nitrogen. For carbon/MEG-BMI composites, their glass transition temperatures were around 400 degrees C; their flexural strength and moduli were maintained at a range of 488.87-575.47 MPa and 48.84-60.26 GPa, respectively. With the increasing content of BMI in the resin formulation, the flexural properties decreased; comprehensively the composite with the eugenol/maleimide unit ratio (1:0.3 mol) had the best mechanical and thermal properties, meanwhile its renewable carbon content was as high as 57.80%. As a new candidate of high temperature thermosetting resin, MEG would find promising applications for advanced composites' matrice.
