2. Description of the Related Art It is known that a 5-membered ring dithiocarbonate derivative can be obtained under a mild condition by using oxirane and carbon disulfide [Journal of Organic Chemistry (J. Org. Chem.), 60, 473]. (1995)]. The derivative gives a functional group having an active proton such as an amino group and a ring-opening adduct very quickly [Journal of Polymer Science, P.A. Polymer Chemistry (J. Po.
lym.Sci., PartA: Polym.Chem.), 33 , 1005 (1995), Macromolecules. , 28, 5387 (1995)], and paints utilizing this reactivity are known. And it is useful as a polymer crosslinking agent such as an adhesive. In addition, polydithiocarbonate obtained by ring-opening addition polymerization as described above can increase the refractive index by introducing an aromatic ring, and thus is expected to be applied to optical materials.
