Copolymerization of Phenanthrene and Maleic Anhydride

Yasuharu Nakayama, Koichiro Hayashi, Seizô Okamura

Abstract

A study of the copolymerization of phenanthrene and maleic anhydride was carried out at 60°C using AIBN as a radical initiator. The copolymerization is characterized by the fact that these two monomers are hardly homopolymerized, and the complex formed by the two monomers may promote the copolymerization. Also, it was found that solvents having no ability to complex with monomer were good milieus for this copolymerization. The copolymers so obtained have 1:2-1:1 composition ratios of phenanthrene and maleic anhydride. Kinetic studies of the copolymerization were carried out under heterogeneous and homogeneous conditions in benzene and dioxane, respectively. [η] of the copolymer in tetrahydrofuran at 30°C was found to be in the range 0. 06-0.13.
