摘要

An olefinically unsaturated monomer is stabilized by a retarder-containing composition which comprises a solvent and a quinone methide as a retarder.

1. A monomer composition, comprising:
an olefinically unsaturated monomer; and from 10 ppb (m/m) to 100 000 ppm (m/m), based on the olefinically unsaturated monomer, of at least one retarder (B) of the formula (II) wherein X=halogen, —O—R3 or —S—R3, R1, R2 and R3=hydrogen, alkyl having 1 to 15 carbon atoms, cycloalkyl having 3 to 15 carbon atoms or aryl group having 6 to 14 carbon atoms, wherein the substituents R1, R2 and R3 are the same or different and are substituted or unsubstituted.
