    Abstract: Novel polyurea compounds having the general formula ##STR1## where R.sub.1 is hydrogen, alkyl, cycloalkyl, aryl, substituted aryl, aralkyl, or a piperidine radical of the formula ##STR2## where R.sub.5, R.sub.6, R.sub.8 and R.sub.9 are alkyl and R.sub.7 is hydrogen, oxygen, alkyl, alkenyl, alkinyl or aralkyl, R.sub.2 is alkylene, cycloalkylene, arylene or aralkylene, R.sub.3 is a piperidine radical as set forth above, R.sub.4 is alkylene, cycloalkylene, arylene or aralkylene, X is zero or one, y is an integer from 2 to 200 and A and B each represent a terminal group. In some of the y units and in B the ##STR3## can be replaced in part by ##STR4## where R.sub.10 R.sub.11 and R.sub.12 are hydrogen, alkyl, cycloalkyl, aryl, aralkyl or R.sub.10 and R.sub.11, are linked together so that ##STR5## forms a 6 to 8 member heterocyclic ringAre produced by reacting a diamine with carbonyl chloride or a diisocyanate. The compounds are valuable light stabilizers for synthetic polymers, particularly polypropylene and polyethelene.
