Method for producing liquid-crystalline polyester powder
Kohinata, Hosoda and  Okamoto of Sumitomo Chemical Company, Japan, produced a liquid-crystalline polyester powder by melt polycondensation of monomers and/or its acylated monomers to obtain a corresponding polyester having a flow initiation temperature of 240 to C.; spreading and solidifying the polyester so as to be a layer thereof with a thickness of 1 cm or more: crushing the solidified substance to obtain a powder having a volume average particle diameter of 3 to 30 .mu.m; and subjecting the powder to a heat treatment to obtain a powder having a flow initiation temperature higher than the flow initiation temperature of the liquid-crystalline polyester after the melt polycondensation.  (RDC 5/29/2012)
