The present invention generally relates to compounds and methods for inhibiting the radical polymerization of unsaturated compounds, particularly vinyl monomers. More particularly, it relates to the use of cinnamyl quinone methides to inhibit the polymerization of unsaturated hydrocarbon compounds (e.g., vinyl monomers) soluble in organic solvents, particularly hydrocarbon streams.

Poly-t-butyl-cinnamyl phenols and poly-t-butyl-dihydrocinnamyl phenols are disclosed to be useful for inhibiting the growth of mosquito larvae, thus providing means for controlling mosquito populations.
Compositions of ultraviolet degradable thermoplastic resins which include low levels of 2-hydroxy-3,5-disubstituted derivatives of 2-aryl-2H-benzotriazoles provide excellent protection against UV-degradation and show virtually no yellowing in aquoeus solutions which contain trace amounts of metals.
