Oxybutane compounds are important raw materials for high-end cationic light-curing products, and their application research began in 2008, when Japan's East Asia Synthesis Company disclosed a series of oxybutane-based monomers and zwitterions in wo2008110512 patent, which have the advantages of low viscosity, small curing shrinkage, and fast curing speed. In recent years, research on oxybutane-type monomers has gradually attracted industry attention, such as igarashi et al. in us5674992 patent discloses curable cationic coating compositions, which contain epoxy (such as ethylene oxide) compounds and oxybutane compounds, the composition does not contain solvents, and the viscosity can be adjusted by adjusting the ratio of components; takami et al. in us5721020 patent discloses a UV-curable coating composition for can packaging containing a cationically polymerizable compound, a compound with at least one oxetane group, a cationic initiator, and an additive that can be used on a variety of substrates. These oxetane compounds generally have low viscosity, low toxicity, fast polymerization speed, excellent thermal stability and mechanical properties, etc., and can be applied to cationic curing systems to accelerate the polymerization speed and improve the performance of the cured products.
