Abstract
A process for preparing a coated article which includes the step of electromotively coating an article molded or extruded from a composition having a conductivity of at least about 10.sup.-14 Siemens/cm (S/cm) comprising (a) a thermoplastic polymer, thermoset polymer, or mixture thereof and (b) an electronically conductive charge transfer complex or inherently semiconducting polymer different from (a). It has been discovered that the process of the invention provides a means by which electromotively coated polymer articles may be conveniently prepared.
Claims21
A process for preparing a coated article which includes the step of electromotively coating an article molded or extruded from a composition having a conductivity of at least about 10.sup.-14 S/cm, which comprises (a) a thermoplastic polymer, reactive components for preparing a thermoset polymer, or a mixture thereof, and (b) an electronically conductive charge transfer complex or inherently semiconducting polymer different from (a), provided that if component (a) is a thermoplastic polymer, the composition is molded or extruded at a temperature above the glass transition temperature of the polymer.
A process for preparing a coated article which includes the step of electrostatically coating an article molded or extruded from a composition having a conductivity of at least about 10.sup.-14 S/cm, which comprises (a) a thermoplastic or thermoset polymer, and (b) an electronically conductive charge transfer complex or inherently semiconducting polymer different from (a), provided that if component (a) is a thermoplastic polymer the composition is molded or extruded at a temperature above the glass transition temperature of the polymer.
A process for preparing a coated article which includes the step of electroplating an article molded or extruded from a composition having a conductivity of at least about 10.sup.-5 S/cm, which comprises (a) a thermoplastic or thermoset polymer, and (b) an electronically conductive charge transfer complex or inherently semiconducting polymer different from (a), provided that if component (a) is a thermoplastic polymer, the composition is molded or extruded at a temperature above the glass transition temperature of the polymer.
