Abstract: Methods and compositions are provided for inhibiting the polymerization of a vinyl aromatic monomer, such as styrene monomer, during elevated temperature processing thereof or during storage or shipment of polymer containing product. The methods comprise adding from about 1-10,000 parts of an aliphatic nitroso compound (ANC) to the monomer, based upon one million parts of the monomer. The compositions comprise a combination of ANC (I) and dinitrophenol (II) and/or quinone methide (III) dissolved or dispersed in a liquid carrier.
