FIELD: polymer production. ^ SUBSTANCE: composition stabilized against oxidative, thermal, or phitoinduced degradation and containing polymer and stabilizer, the latter being product of reaction of 2-4 equivalents of 2,4-bis[(1-hydrocarbyloxy-2,2,6,6-tetramethylpiperidine-4-yl)alkylamino]-6-chloro-s-triazine, wherein hydrocarbyl denotes methyl, octyl, or cyclohexyl radical, with 1 equivalent of N,N'-bis(3-aminopropyl)ethylenediamine, is claimed. Method of preparing stabilizer is described. ^ EFFECT: enlarged choice of stabilized polymer compositions. ^ 8 cl, 30 ex |
