Derivatives of 1-oxyl-4-amino-2,2,6,6-tetramethylpiperidine as polymerization inhibitors for (meth)acrylate monomers

摘要

Selected derivatives of 1-oxyl-2,2,6,6-tetramethyl-4-aminopiperidine are surprisingly effective as inhibitors to prevent the premature polymerization of acrylic and methacrylic acids, their esters, their amides, vinyl acetate and acrylonitrile in the presence of water.
