Compositions and methods for inhibiting vinyl aromatic monomer polymerization

Methods and compositions are provided for inhibiting the polymerization of vinyl aromatic monomers under distillation conditions. The compositions comprise a combination of a phenylenediamine compound and a hydroxylamine compound.

Stabilization of unsaturated carboxylic acid esters with mixtures of polyalkylene-amines and arylenediamines

A method of inhibiting polymerization of unsaturated carboxylic acid esters and improved unsaturated carboxylic acid ester compositions are described. The method comprises, and the compositions are prepared by, incorporating into the ester composition a combination comprising polyalkyleneamine and arylenediamine of the formula STR1 in which X is hydrogen, chloro, trichloromethyl, trifluoromethyl, nitro, lower alkyl, lower alkoxy or phenoxy, R is hydrogen or alkyl, and R1 is alkyl or phenyl or R and R1 together with the nitrogen atom is a heterocycle selected from the group consisting of pyrrolidinyl, 2,5-dimethyl pyrrolidinyl, piperidino and hexahydro-1H-azepin-1-yl.
