The present invention provides a liquid crystal polyester composition, comprising (i) 100 parts by weight of a liquid crystal polyester, and (ii) 65 to 100 parts by weight of a combination of a fibrous filler with a plate-like filler, wherein the fibrous filler has a number-average fiber diameter of 5 to 15 μm, and a number-average aspect ratio of 20 to 40, and a content ratio by weight of the fibrous filler to the plate-like filler is more than 1.0 and 1.6 or less; and a process for producing the liquid crystal polyester composition comprising a step of melt-kneading the above respective components with one another.
摘要:
The present invention provides a dispersion in which aromatic polysulfone resin particles are dispersed in water. The aromatic polysulfone resin particles comprises a aromatic polysulfone resin having oxygen-containing groups selected from among hydroxyl groups and oxyanion groups in an amount of 1.6 or more groups relative to 100 repeating units forming the aromatic polysulfone resin; and have the volume average particle diameter of 50 μm or less. The dispersion is less likely to cause settlement of the aromatic polysulfone particles and is suited for use as an aqueous coating material.
