FIELD: chemical industry. SUBSTANCE: new oligomeric compounds of formula I: wherein L is group of formulae IV and V, oxygen in group L is bonded with phosphorus in recurring structural unit and residue R2 in corresponding case, or carbon in position 4 of piperidine ring of group L is bonded with oxygen of recurring structural unit, R1 is C1-C8 alkyl, C5-C8 cycloalkyl or tetrahydrobietyl; R2 is C1-C8 alkylene; m is 0-1, n is 2-10 are suitable for stabilization of organic material against oxidative, thermal and light- induced destruction. Also claimed are method of preparing compounds of general formula I by reacting compound of formula II with compound of formula III, polymeric composition comprising organic material subjected to oxidative, thermal or light-induced destruction, method of stabilization of organic material against oxidative, thermal and light-induced destruction. EFFECT: more efficient preparation and stabilization methods. 12 cl, 5 ex, 3 tbl ![](/patent/RU2132852C1/i/00000006.png)
