POLYMERIC/POLYIMIDE COMPOSITIONS HAVING ENHANCED ELECTROSTATIC DISSIPATION

摘要

The subject invention relates to an electrostatic dissipative polymeric composition. It has been found that the incorporation of a polyimide into a basepolymer 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 tobe adopted for specific applications that cannot be normally achieved without the enhanced properties. 1900018
