Abstract: The amino-silicone was prepared by hydrosilylation of hydrogen-silicone with a llyl amino.The amino-value of the amino-sili cone is 0.8～1.5, and then inserted the alkoxy group into the structure to imp rove the crosslink ability.The optimal reactive condition was the toluene as sol vent,H₂PtCl₆ catalyst content 0.2 mmol/g and added the allyl amino to hyd rogen-silicone dropwise within 2 hours under reflux.Kept the temperature to r ea ct 2～3 h,then added n-propanol containing KOH in 30 minutes and reacted 90 m inutes to gain amino-silicone containing alkoxy group.
