摘要：

These flat elliptical polymer particles have a front view, a planar view, and a side view in a projection diagram based on third-angle projection which are all elliptical. The flat elliptical polymer particles satisfy (1)-(4): (1) the average length (LAV) of flat portions satisfies 0.13≤(LAV)≤500 μm； (2) the average breadth (DAV) of the flat portions satisfies 0.1≤(DAV)≤250 μm； (3) the average (P1AV) aspect ratio (L/D) calculated from the length (L) and the breadth (D) satisfies 1.3<；P1AV≤50； and (4) the average (P2AV) aspect ratio (D/T) calculated from the breadth (D) and the thickness (T) of the side surface satisfies 1.2<；P2AV≤100.
