Abstract: Polymerization inhibitor compositions are provided. The polymerization inhibitor compositions may include at least one hydroxylamine of a nitroxide and at least one phenylenediamine. Methods of inhibiting the unwanted polymerization of monomers are also provided. The methods include adding the presently disclosed polymerization inhibitor compositions to a fluid containing the monomers. The monomers may be ethylenically unsaturated monomers, such as acrylic acid, methacrylic acid, acrylonitrile, methacrylonitrile, acrolein, methacrolein, acrylate, methacrylate, acrylamide, methacrylamide, vinyl acetate, butadiene, ethylene, propylene, and styrene.

Abstract: Disclosed herein are compositions including between 20 wt % and 50 wt % of a nitroxyl compound such as 2,2,6,6-tetramethylpiperidinyl-1-oxyl. The compositions are stable under field conditions of transportation and storage. The compositions remain homogeneous and pumpable or pourable at temperatures between −20° C. and 60° C., even when temperatures fluctuate in this range over a period of 10 days to 5 years, and even where the container used to transport and store the composition is made from metal or includes a metal surface contacting the composition.

Abstract: The present invention generally relates to a method for reducing polymer agglomeration or fouling, and its use in processes for the preparation of an acrylate, methacrylic acid, or a methacrylate. According to the present invention, the reagent comprises an alkyl phthalate, an alkaryl phthalate, an aryl phthalate, or a phthalic acid, and applying the reagent to processes for the preparation of an acrylate, methacrylic acid, or a methacrylate to prevent polymeric foulant precursors from agglomerating or to dissolve existing polymeric agglomerates or foulants so as to reduce polymer agglomeration or fouling in the process or storage equipment.
