Abstract

A polymerizing fluid polymer (thermoplastic, elastomer, thermoset polymer, thermoplastic elastomer, thermoplastic vulcanizate) with an optional filler (such as magnetizable ferrite powder or carbon nanotubes) is extruded or pultruded into shaped polymer (optionally multilayer shaped polymer) so that all portions of the shaped polymer conform within a desired state of polymerization (in a multilayer coating, that the quality-related performance characteristics of shaped polymer are consistent within any coating layer). At least one (tear-drop shaped) flow diverter is described for diverting flow within an extrusion (pultrusion) die so that fluid polymer moving through a short residence time portion of the die will have a more substantial residence time (than would be the case if the diverter were not used) with commensurately greater thermal, pressure, and shear stress history so that the desired conformance respective to polymerization states for all portions in the shaped polymer is achieved.
