Abstract
The present invention generally relates to compounds and methods for preventing fouling caused by the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of hindered hydroquinones to inhibit the polymerization, which result in the fouling of process equipment, and prematurely consume the vinylic monomer products.
