Patent ID: 7435770

Claim:
A product which comprises an antistatic polymer composition containing not less than 0.1 parts by weight nor more than 65 parts by weight of a polymeric antistatic agent, and 100 parts by weight of at least one polymer selected from the group consisting of a thermoplastic polymer, a thermoplastic elastomer, and an unvulcanized rubber, wherein said polymeric antistatic agent comprises a polymer composition containing a polymeric charge prevention agent containing a resin and/or an elastomer as a main component thereof; and/or a thermoplastic resin having a polar group or/and an elastomer having said polar group; and an anion-containing salt, having at least one anion selected from chemical formulas 1 and 3 shown below, which is added dispersedly in said polymer composition without the intermediary of a medium, consisting of a low-molecular-weight polyether-containing compound or a low-molecular-weight polar compound with a number-average molecular weight of not more than 5000, wherein chemical formula 1 is as follows: and chemical formula 3 is as follows: where X1, X2, and X3 denote functional groups containing C, —F, and —SO2- and having one to eight carbon atoms, and wherein said polymer composition contains a polyether block polyolefin copolymer.
