Design and Preparation Technology of Single/Dual-Cross-Linking Copolymers Based on Swida wilsoniana Oil
To fully utilize the forestry bioresources, a novel dual-cross-linkable resin monomer of MAHSWAGMA was prepared from Swida wilsoniana oil (SWO). FT-IR and 1H-NMR analysis demonstrated the successful synthesis of the target product. Five different cross-linking copolymers, including a polymerized vinyl ester/single-cross-linking (PVESC) polymer, a polymerized epoxy/single-cross-linking (PESC) copolymer, a thermal-photo-initiated/dual-cross-linking (TPIDC) copolymer, a photo-thermal-initiated/dual-cross-linking copolymer (PTIDC), and a thermal-initiated/dual-cross-linking copolymer (TIDC), were obtained with different preparation technologies by different initiated cross-linking processes. Thermal and mechanical properties of the five copolymers were all tested, and the effects of different preparation technologies on the properties of prepared copolymers were investigated. The prepared three dual-cross-linking copolymers had higher hardness, relative cross-linking density, glass transition temperature, and more excellent mechanical property than the other two single-cross-linking copolymers. The PTIDC copolymerized system obtained with photo first and thermal latter initiated dual-cross-linking preparation technology had the most excellent comprehensive properties. This study can provide an ideal idea for the design and preparation of dual-cross-linking copolymers based on forestry vegetable oil.
