in the presence of isopropyl alcohol,amino polyether co-modified silicones(AEMPS) was obtained by ring-opening reaction of epoxy group polyether with amino silicone(APS).Its chemical structure was characterized by IR.The application properties of AEMPS were also studied.The results indicated that the optimum experimental conditions were that reaction temperature 70℃,reaction time 6h,the mass ratio of APS to epoxy group polyether 2∶1,solvent dosage 60%(relative to amino silicone and epoxy group polyether tot...
