ABSTRACT:
Chain extended random alkoxylated polyols having branched configurations are useful as internal antistatic additives for polymeric structures. A polyol having a branched configuration is alkoxylated with a mixture of ethylene oxide and propylene oxide and then chain extended to produce a high viscosity fluid additive which is compatible as a dispersed phase with polymer melts and does not agglomerate or separate from the melt during spinning. From about 0.1% to about 15% by weight of the additive is incorporated in polymeric structures as an antistatic agent. A useful additive composition is obtained using pentaerythritol tetrapropoxylate as the polyol and Bisphenol A diglycidyl ether as the difunctional reactant.
