Abstract
The present invention uses high molecular weight polyethene glycol copolymer with high antistatic property, and other solubilizer agent to proceed blending and enhancing the co-solublization property of the polyamide. The long-term antistatic plastic particles obtained by blending the modified antistatic composition and the polyamide material are made into different articles according to various composites. The molded articles are divided into three types: (1) an antistatic polyamide article with surface resistance of about 10.sup.10 -10.sup.11 (.OMEGA./sq.), and the dissipation time of electrostatic charge is less than 1.5 sec; (2) an antistatic polyamide fiber with surface resistance of about 6.times.l0.sup.10 -1.2.times.10.sup.12 (.OMEGA./sq.), and the dissipation time of electrostatic charge is less than 60 sec; (3) a polishing resistant antistatic polyamide with surface resistance of about 10.sup.10 -10.sup.11 (.OMEGA./sq.), and the dissipation time of electrostatic charge is less than 1.5 sec.
