This paper introduced the synthesis of alkoxyl-terminated polysiloxane with potassium trimethyl-silanolate, sodium fatty alcoholate, cyclohexanone oxime, dibutyl tin diacetate and tetramethyl ammonium hydroxide as the catalysts. The effects of type and amount of catalysts on the synthesis reaction of alkoxyl-terminated polysiloxane and the tack-free time and electrical properties of dealcoholized silicone sealant were investigated.
