20130015411	METHOD FOR MANUFACTURING A WHOLLY AROMATIC POLYIMIDE POWDER HAVING AN ANTISTATIC OR CONDUCTIVE PROPERTYAANM Kang; Jin SooAACI DaejeonAACO KRAAGP Kang; Jin Soo Daejeon KRAANM Hwang; Yong JaeAACI Bucheon-siAACO KRAAGP Hwang; Yong Jae Bucheon-si KR - The present invention relates to a method for preparing wholly aromatic polyimide powder with antistatic properties or electric conductivity. In particular, the present invention relates to a method for preparing wholly aromatic polyimide composite powder, comprising the steps of dissolving aromatic diamine in a phenolic polar organic solvent in which electrically conductive carbon black powder and multi-wall carbon nano-tube (MWCNT) powder are dispersed, adding aromatic tetracarboxylic dianhydride thereto, and polymerizing the resulting mixture.	01-17-2013
20120277401	METHOD FOR MANUFACTURING A WHOLLY AROMATIC POLYIMIDE RESIN HAVING IMPROVED HEAT RESISTANCE AND ELONGATION PROPERTIES IN A HIGH TEMPERATURE RANGE - The present invention relates to a method for preparing wholly aromatic polyimide resin with improved heat-resistance. In particular, the present invention provides a method for preparing polyimide resin having enhanced heat-resistance and superior mechanical properties, especially elongation rate and tensile strength at high temperature through liquid polymerization of two kinds of aromatic tetracarboxylic dianhydrides and aromatic diamine whose mixed ratio is properly regulated.	11-01-2012
