P-Hydroxydiphenylamine

A vinyl monomer that acts as an antioxidant is 4-anilino-N-(4-vinylbenzyl)aniline, which can be prepared from p-aminodiphenyl-amine and p-chloromethylstyrene. Similarly, the reaction product of p-hydroxydiphenylamine and p-chloromethylstyrene, which is 4-anilinophenyl-4-vinylbenzyl ether is useful in this way (72). The synthesis is shown in Figure 6.11.
