Abstract
The present disclosure provides compositions and methods for inhibiting or preventing fouling. A method of inhibiting polymerization of an ethylenically unsaturated monomer in a medium may include adding an effective amount of a composition to the medium. The composition includes a polymerization inhibitor, such as HTEMPO sebacate. Examples of ethylenically unsaturated monomers include acrylic acid, methacrylic acid, acrylonitrile, methacrylonitrile, acrolein, methacrolein, acrylate, methacrylate, acrylamide, methacrylamide, vinyl acetate, butadiene, ethylene, propylene, styrene, and any combination thereof.
Claims16
A method of inhibiting polymerization of an ethylenically unsaturated monomer in a medium, comprising:
- adding an effective amount of a composition to the medium, the composition comprising a polymerization inhibitor of the following structure:
- wherein each R1, R2, R3, and R4 is independently selected from a substituted or unsubstituted C1-C10 alkyl group, a C1-C10 alkenyl group, or a C1-C10 alkynyl group;
- each R5 is independently selected from H, OH, or O;
- and
- n is an integer from 1 to 50;
- and
- inhibiting polymerization of the monomer.
