ABSTRACT:
By reacting polyalkyl-piperidones-4 with the 0.5- to 1.1-molar amount of formaldehyde in the presence of an aliphatic monoalcohol at 50.degree. to 180.degree. C., polymers of a polymerization degree of from 2 to about 200 are obtained, which may be hydrogenated or partially hydrogenated. Especially in this form, they are suitable as light stabilizers for synthetic polymers and as intermediate products for the preparation of other stabilizers for plastic materials.
