    Abstract: Please be informed that the "follow up required item" does not work properly. For TOC and SL indication there is a follow-up required item although there is no warning in Bibadmin. See following example : A vinyl monomer polymerization inhibitor composition comprising a liquid mixture comprising a vinyl monomer and a polymerization inhibiting effective amount of a captive polymerization inhibitor, wherein the composition lacks a fugitive polymerization inhibitor of polymerization of the vinyl monomer and the captive polymerization inhibitor independently is characterizable as being an inhibitor of polymerization of the vinyl monomer and polymerization of the vinyl monomer is inhibited by the captive polymerization inhibitor, and wherein the captive polymerization inhibitor is a compound of formula (I): or a first acid addition salt thereof, wherein R1 is hydrogen or (C1-C3)alkyl.
