Organosilicon foam stabilizer is synthesized by D4 ring opening polymerization, copolymerization and hydrosilylation methods with D4 , high hydrogen containing silicone oil and polyether as raw materials, which is an important foam stabilizer and emulsifier in polyurethane foams. D4 ring opening polymerization is one of the key of the preparation of organosilicon foam stabilizer. The research progress on mechanism and kinetics of D4 ring opening polymerization were introduced. The reference data and theoretical basis were provided for development and produc-tion of organosilicon foam stabilizer.
