| titleOfInvention | Graded-refractive-index optical plastic material and method for its production |
| abstract | A graded-refractive-index optical plastic material comprising an amorphous fluorine-containing polymer (A) having substantially no C-H bond, and at least one fluorine-containing polycyclic compound (B) having a refractive index higher by at least 0.005 than the fluorine-containing polymer (A), wherein the fluorine-containing polycyclic compound (B) is distributed in the fluorine-containing polymer (A) with a concentration gradient such that the concentration decreases in a direction of from the center to the periphery, and the fluorine-containing polycyclic compound (B) is at least one fluorine-containing polycyclic compound selected from the group consisting of the following compounds (B1), (B2) and (B3): (B1) a fluorine-containing non-condensed polycyclic compound having at least two fluorine-containing rings bonded by a bond containing at least one member selected from the group consisting of a triazine ring, an oxygen atom, a sulfur atom, a phosphorus atom and a metal atom, each of said fluorine-containing rings being a carbon ring or a heterocyclic ring and having a fluorine atom or a perfluoroalkyl group, said polycyclic compound having substantially no C-H bond; (B2) a fluorine-containing non-condensed polycyclic compound having at least three fluorine-containing rings bonded directly or by a bond containing a carbon atom, each of said fluorine-containing rings being a carbon ring or a heterocyclic ring and having a fluorine atom or a perfluoroalkyl group, said polycyclic compound having substantially no C-H bond; (B3) a fluorine-containing condensed polycyclic compound which is a condensed polycyclic compound composed of at least three carbon rings or heterocyclic rings, and which has substantially no C-H bond. |
