Description and Uses

4-Methoxystyrene (Para-methoxystyrene) is an important chemical raw material, can replace styrene compounds, and is widely applied to various fields such as a light polymerization inhibitor, a material, a medical intermediate, a pesticide, an adhesive, a coating, a sun-screening agent and the like. Besides, the p-methoxystyrene can be used as a polymerization monomer to synthesize polymers with different structures, and the synthesized polymer contains a protecting group which is easily subjected to acidolysis by light so that the p-methoxystyrene can be used as an excellent corrosion-resistant material to be applied to the electronic information industry.

4-Methoxystyrene is employed in the ferric chloride-catalyzed addition of activated methylenes to styrenes. It acts as a monomer in polymerization reactions. Further, it is used to prepare 1,1,2,2-Tetracyano-3-(p-methoxyphenyl)cyclobutane by reacting with ethenetetracarbonitrile.
