OVAL-SPHERICAL ORGANIC POLYMER PARTICLE AND PROCESS FOR PRODUCING THE SAME |
摘要 |
Oval-spherical organic polymer panicles having ionic functional groups, which have each one continuous curved surface whose aspect ratio calculated by the formula: aspect ratio (P 1 ) = major axis (L 1 )/minor axis (D 1 ), wherein the major axis (L 1 ) and minor axis (D 1 ) are those of a projection two-dimensional drawing obtained by light irradiation in the direction orthogonal to the direction of major axis of the panicle, satisfies the relationship (P 1 ) ‰¥ 1.8. The obtained particles excel in optical properties, such as light scattering and light focusing, and frictional properties, such as sliding characteristic.
