    摘要： Reactive stabilizing compounds, able to stabilize organic polymers, contain in their molecule a sterically hindered amino group and a hydrolyzable silyl function.In stabilizing organic polymers, said reactive stabilizing compounds can be hydrolyzed at the silyl function with the formation of silanol groups, which are made to interact in order to form complex resinous stabilizing structures. These latter are added in stabilizing quantities to the polymer to be stabilized.According to one particular embodiment, the hydrolysis at the silyl function and the formation of the resinous structure take place spontaneously within the polymer to be stabilized.According to a further embodiment, the reactive stabilizing compound is added to the polymer after being stably supported on a solid support by reaction with an inorganic solid having surface hydroxyl groups.According to a further embodiment, the reactive stabilizing compound is made to interact with the polymer so that the stabilizing compound becomes chemically bonded to the polymer chains.In all cases, stabilized polymers are obtained containing the stabilizing compound in a form which is not removable from the polymer.The processes for preparing the reactive stabilizing compounds and for preparing the stabilized polymer compositions are also described.
