| Abstract：Hydroxgyisopropyl-silicone was prepared by hydrosilyation reaction using allylalcohol and hydrogxysilicone,and the reaction was catalysted by chloroplatinic.The yield of this reaction was determined using chemistry titration by which the unreacted active hydrogen was detected.The product was characterized by FT-IR.The synthesis process conditions are investigated by experiments.When hydrogxysilicone∶ allylaicohol was 4∶1(v/v) and chloroplatinic amount is about 0.003% at 900C for 4 hours,the yield of reactio... |
