ABSTRACT:
An anti-static resinous composition with permanent anti-static property is provided. The anti-static resinous composition comprises from 5 to 50 percent by weight of hydrophilic copolymer and from 50 to 95 percent by weight of thermoplastic. The hydrophilic copolymer is formed by self-emulsion polymerization. The monomer mixture used in the reaction comprises from 10 to 70 percent by weight of vinyl or propenyl macromonomer containing a polyethylene oxide chain and from 30 to 90 percent by weight of ordinary vinyl monomer. The thermoplastic is compatible with the hydrophilic copolymer. The resultant resinous composition has permanent anti-static properties.
