Abstract:
A polyetheresteramide having good heat resistance, permanently antistatic property and superior compatibility with thermoplastic resins and a resin composition containing the polyetheresteramide are disclosed. The polyetherester-amide consists essentially of a polyamide oligomer with carboxylic chain ends having a number average molecular weight between 200 to 5,000 and a bisphenol compound with oxyalkylene units having a number average molecular weight between 300 to 3,000. Antistatic resin compositions with good antistatic property and heat resistance are obtained from compositions comprising 3 to 40 % by weight of the polyetheresteramide and 60 to 97 % by weight of thermoplastic resins. The antistatic resin compositions can contain as compatibilizers vinyl polymers having functional groups such as carboxyl and epoxy groups or block polymers containing polyolefin blocks and aromatic vinyl polymer blocks. To further improve the antistatic property of the resin composition a composition comprising at least 97 % by weight of the polyetheresteramide and at least 0.01 % by weight of an alkali metal or alkaline earth metal halide can be used in the same way as the polyethersteramide.

An antistatic agent for thermoplastic polymers is provided wherein the antistatic agent is comprised of a functionalized alkylene oxide polymer and optionally a minor amount of an alkali or alkaline earth metal salt capable of complexing with the functionalized alkylene oxide polymer and wherein the thermoplastic polymers include styrenic polymers such as ABS ; blends of an ABS copolymer and a styrene-maleic anhydride copolymer; or nylon 6.
Abstract:
The subject invention relates to an electrostatic dissipative polymeric composition. It has been found that the incorporation of a polyimide into a base polymer will enhance the electrostatic dissipative properties (ESD) of the composition comprising a base polymer and an ESD additive. This enhancement of the ESD properties is illustrated by the decrease in both the surface resistivity and volume resistivity. In compositions employing the same ESD additive this enhancement provided by the incorporation of the polyimide could allow a reduction of electrostatic dissipative additive required to achieve acceptable results. Further, the improved properties could allow the material to be adopted for specific applications that cannot be normally achieved without the enhanced properties.
