Process and performance aid for carbon nanotubes

摘要

A polymer composition which includes carbon nanotubes in a resin matrix such as cyclic butylene terephthalate where the resin matrix is compounded into a polymer matrix. The carbon nanotube resin matrix is compatible in a wide variety of polymer matrixes having many end uses. The resin matrix provides good compatibility with many polymer systems, e.g., polyamides, polyesters, acrylics and is easy to use exhibiting a low melting point and low viscosity in melt and provides for a polymer matrix having good properties, including a higher electrical conductivity and/or increased mechanical properties.
