    Abstract: Polyphenylene sulfide microparticles have a linseed oil absorption amount of 40 to 1,000 mL/100 g and a number average particle diameter of 1 to 200 μm. The porous PPS microparticles have a large specific surface area and therefore promote fusion of particles when molded into various molded bodies by applying thermal energy, thus enabling formation or molding of a coating layer of particles at a lower temperature in a shorter time. The porous PPS microparticles have a porous shape and therefore enable scattering light in multiple directions and suppression of specific reflection of reflected light in a specific direction, thus making it possible to impart shading effect and matte effect when added to a medium.

    Abstract translation: 聚苯硫醚微粒的亚麻子油吸附量为40〜1000mL / 100g，数均粒径为1〜200μm。 多孔PPS微粒具有大的比表面积，因此通过施加热能而成型为各种成型体时可促进粒子的熔融，从而能够在更短的时间内在较低的温度下形成或成型粒子的涂层。 多孔PPS微粒具有多孔形状，因此能够在多个方向上散射光并抑制反射光在特定方向上的特定反射，从而可以在添加到介质中时赋予遮光效果和无光泽效果。

    Abstract: A method for the manufacture of a solid porous separation material based on a polysaccharide, said method comprising the steps of: (a) providing an aqueous solution (I) of a polysaccharide, (b) solidifying the solution, preferably by transforming the solution to a gel, and (c) optionally cross-linking the polysaccharide, with the proviso that, if step (c) is present, steps (b) and (c) may be carried out simultaneously. The method is characterised in that the polysaccharide provided in step (a) is modified by being inter-molecularly cross-linked to an extent such that the viscosity of solution (I) is at least 110%, preferably at least 200%, of the viscosity of an aqueous solution (II) of the corresponding polysaccharide which has not been inter-molecularly cross-linked and which is present in the same concentration as the inter-molecularly cross-linked polysaccharide is in solution (I).
