Abstract
o-Hydroxyohenyl-s-triazines containing suitable functional groups are incorporated in polymers by copolymerisation, copolycondensation, copolyaddition or by polymer-analogous reaction. The modified polymers so obtained have excellent stability to degradation induced by light, oxygen and heat. They can also be used as stabilisers.
