2-Vinylnaphthalene is employed in the synthesis of various copolymers such as Poly (sodium styrenesulfonate-co-2-vinyl-napthalene) copolymer?and Poly (2-vinylnapthalene-alt-maleic acid)-graft-polystyrene. The latter finds applications as a photoactive polymer micelle and stabilizer for polystyrene latexes.
