    Abstract: Disclosed are non-spherical resin particles that allow for improvement of light diffusion, light reflection, and other related properties, and a manufacturing method thereof. The particles comprise first and second, different resin components (1) and (2), with the second resin component (2) residing locally near the surface of the non-spherical resin particles. The method of manufacturing non-spherical resin particles involves either allowing particles of a resin to absorb a vinyl-based polymerizable monomer contained in an aqueous emulsion followed by polymerization of the absorbed monomer or dissolving a resin in a vinyl-based polymerizable monomer followed by polymerization of the obtained solution in an aqueous medium. In the method, the resin has a site derived from a (meth)acrylic acid ester having a C2-C10 halogenated alkyl group or alicyclic hydrocarbon group and has a weight-average molecular weight of from 150,000 to 1,000,000. The vinyl-based polymerizable monomer contains 5 to 50 wt % crosslinking monomer.

    Abstract: A synthetic wood being an elongated microporous article formed of a plurality of coalesced, foamed resin strands, each being in intimate contact with each other, and each having a higher density in its outer surface and lower density in its inner portion. Thus, the cross section of the synthetic wood comprises a frame distributed in a reticulate form. The synthetic wood of the invention is produced by extruding softened thermoplastic resin containing expanding agents into a plurality of expandable strands by passing the same through a die at the discharge end of an extruder, the die having a number of apertures and coalescing the strands into a microporous article having a desired crosssectional area while the strands are still in a softened state, wherein the space in which each individual strand is allowed to expand is restricted to provide each of the strands with a higher density outer surface.
