POLYMERIZATION INHIBITOR COMPOSITIONS, THEIR PREPARATION, AND THEIR USE

摘要

This invention provides a polymerization inhibitor composition in the form of a solution. The solution is formed from ingredients comprised of: a) tris(N-nitroso-N-phenylhydroxylamine)aluminum salt and b) at least one liquid ethoxylated phenol acrylate of the formula: PhO(CH₂CH₂O)_nC(O)CH=CH₂ wherein n is an integer of 2 or more; or c) at least one liquid alkyl methacrylate or at least one liquid alkanediol dimethacrylate, or both; or d) both of b) and c); the amount of a) used in forming said solution being at least about 1 wt% based on the total weight of said solution.
