ORGANOSILOXANES, METHOD OF THEIR SYNTHESIS AND POLYMERIC COMPOSITION ON THEIR BASIS

Polymeric stabilizers having a polysiloxane structure contain reactive groups which can be linked to the polymeric structure to be stabilized as well as sterically hindered piperidyl groups. These polymeric stabilizers are particularly suitable for the stabilization of organic polymers against U.V....

Beschreibung
Zusammenfassung:	Polymeric stabilizers having a polysiloxane structure contain reactive groups which can be linked to the polymeric structure to be stabilized as well as sterically hindered piperidyl groups. These polymeric stabilizers are particularly suitable for the stabilization of organic polymers against U.V. radiation and heat when the stabilizer must not be extracted by solvents, fats or soaps.
