Anionic polymerization and polymer properties of 2-isopropenylnaphthalene and 2-vinylnaphthalene

Abstract 2-Isopropenylnaphthalene (2-IPN) and 2-vinylnaphthalene (2-VN) were polymerized in toluene with sec-butyllithium initiator. For 2-IPN, equilibrium monomer concentrations were determined, as well as the enthalpy, entropy and ‘absolute’ ceiling temperature, for its polymerization. Densities of both polymers were measured and their solubility parameters were calculated. They are, respectively, for 2-IPN, 1.105 g cm−3 and 9.2 cal 1 2 cm −3 2 , and for 2-VN, 1.108 g cm−3 and 9.4 cal 1 2 cm −3 2 .
