Abstract: A novel type of dual-crosslinking resin monomer(MA-AEHO) containing carboxyls and vinyls was synthesized using hemp oil (HO) as raw material.The monomer structure was characterized by FT-IR and ¹H NMR. Two single-crosslinking polymers (polymer 1 and 2) and two dual-crosslinking polymers (polymer 3 and 4) were obtained by the polymerization of MA-AEHO with the different curing and cross-linking processes. The properties of four polymers were tested.Mechanical performance tests showed that the tensile strength of polymer 1-4 is 9.21, 14.73, 32.05 and 33.25 MPa, and the elongation at break is 56.21%, 9.97%, 4.56% and 3.18%, respectively. Their tensile strengths were significantly improved and the elongations at break were decreased compared with the single-crosslinking polymers. Dynamic thermal mechanical analysis showed that the dual-crosslinking polymers (polymer 3 and 4) have relatively higher energy storage modulus (32.00 and 41.29 MPa) and glass transition temperature (58.08 and 91.44℃) than those of the single-crosslinking polymers. Thermogravimetric analysis results showed that these four curing polymers possessed good thermal stability, and the initial decomposition temperature of the polymers are all above 300℃.
