ABSTRACT:
The present invention provides a process for inhibition of polymerization of a (meth)acrylate ester, which has an extremely higher effect of inhibition of polymerization than in cases where conventional polymerization inhibitors are used. In the process for inhibition of polymerization of a (meth)acrylate ester; an N-oxyl compound and at least one member selected from the group consisting of manganese salt compounds, copper salt compounds, 2,2,6,6-tetramethylpiperidine compounds, and nitroso compounds are used together as polymerization inhibitors, and further an acid is used.
