FIELD: chemistry.SUBSTANCE: retardant-containing composition (AB) contains: a solvent (A), which is selected from benzene, toluene, ethylbenzene or styrene, and at least one retardant (B) of formula, where X denotes a group -O-R, where Rdenotes an alkyl group with 1-15 carbon atoms, an aryl group with 6-15 carbon atoms and a cycloalkyl group with 3-15 carbon atoms, Rand/or Rdenote a methyl or tert-butyl group, wherein R, Rand Rtype substitutes are identical or different, are added to an unsaturated olefin monomer or to a mixture of monomers which contains at least one unsaturated olefin monomer. The invention also relates to compositions for stabilising unsaturated olefin monomers which use said retardant.EFFECT: improved method.11 cl, 3 tbl, 25 ex, 1 tbl |
