Abstract
Polymeric stabilizers having a polysiloxanic structure contain reactive groups which can be linked to the polymeric structure to be stabilized and sterically hindered piperidinic groups. These polymeric stabilizers are particularly suitable for the stabilization of organic polymers against U.V. radiation and heat, when it is required for them not to be extracted by solvents, fats or soaps.
