Polyalkylpiperidyl ureas, their application as stabilizers and polymers thus stabilized

摘要

polyalkylpiperidyl - urea of the formula i,where m 1 - 4, x, r2 and r3 monohydric substituent and r a m are made of, can from the corresponding four aminopiperidinen by implementation with carbamoylchloriden are produced.they are excellent stabilizers for plastics, in particular for polyolefins, against lichtabbau
