METHOD FOR IMPROVING ELECTRICAL CONDUCTIVITY OF RESIN

摘要

PURPOSE:To improve the electrical conductivity of a resin molding without causing degradation of the physical properties, and coloration of the molding by mixing a resin with a high-molecular compd. obtd. by crosslinking a polyether polyol and a sol. electrolyte salt. CONSTITUTION:The electrical conductivity of a resin is improved by mixing the resin with a high-molecular compd. obtd. by crosslinking a polyether polyol and a sol. electrolyte salt, or by mixing the resin with a complex formed from the high-molecular compd. and the salt. As for the mol.wt. of the high-molecular compd., the higher the better and 10000 or higher is pref. in terms of keeping resin properties unchanged. A synthetic resin in general usually has a surface resistance of 1014OMEGA.cm or higher and tends to be highly charged; however, the resin improved as above has a surface resistance of 1011OMEGA.cm or lower and hence shows remarkable antistatic properties and a high ionic conductivity, and, in addition, these properties are kept stably for a long period.
