1、Synthesis of 24-methylenecholestan-3β,5α,6β-triol
2、With the compounding of polyether glycol and triol, the foam sealant can get good allround properties.
3、Preferably, the urethane prepolymer is an aliphatic isocyanate polyether prepolymer and the curative includes an aromatic diamine and a triol.
4、The synthesis of oxyethylene oxypropylene copolyethers used for quenchant was studied by using anionic ring opening polymerization, diol or triol as the starting agent and KOH as the catalyst.
