Abstract: Insecticided compositions comprising (a) a mixture of methylenedioxybenzene derivative compounds having in the benzene ring one, two and three substituents of the formula --CH.sub.2 O--(CH.sub.2 CH.sub.2 O).sub.2 --R.sub.1 wherein R.sub.1 is hydrogen or an alkyl group having from 1 to 4 carbon atoms and (b) an insecticide selected from the group consisting of synthetic pyrethroids, carbamates, organic phosphorates, avermentines and insect growth regulators.

Abstract: Novel piperidyl triazine derivatives are produced by reacting a substituted halogentriazine with a polyalcohol, a polymercaptan or a polyamine. The compounds are valuable light stabilizers for synthetic polymers, such as polyolefins, and fast to extraction in aqueous surfactant solutions.

Abstract: A composition is described for stabilizing polypropylene homopolymers against the deteriorating effects of light, particularly ultraviolet light, comprising a mixture of (I) benzophenones with (II) metal complexes of related compounds.

Abstract: Novel tetraalkyl piperidine radical containing polytriazine compounds are produced by reacting a dihalogen-triazine with a bifunctional compound containing amine, alcohol, mercaptan or phenol groups at least one of the bifunctional compounds containing a tetraalkyl piperidine radical. The compounds are valuable light stabilizers for synthetic polymers, particularly polyolefin in the form of fibers or films.

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.
