Sodium borohydride was examined as a polymerization inhibitor for methyl methacrylate and found to be more effective than hydroquinone‐type inhibitors in preventing polymerization during monomer storage under nitrogen at elevated temperature. NaBH 4 appears to function by reducing peroxide and hydroperoxide impurities that form during monomer storage. Unlike conventional free radical inhibitors, NaBH 4 does not interfere with azo initiator systems. In peroxide‐initiated systems, the inhibitory effect of NaBH 4 can be overcome by simple acidification.
