ABSTRACT:
Polyalkylpiperidinylesters and N-polyalkylpiperidinylamides of substituted malonic acids, methane tricarboxylic acids, .beta.-keto-, .alpha.-cyano-, .alpha.-phosphono- or .alpha.-sulfonocarboxylic acids are excellent stabilizers for polymers, especially against photochemical degradation. Polymers which can be stabilized in this way very effectively are polyolefins, styrene homo- and copolymers, polyamides and polyurethanes.
