To prepare the blend, the polymers may-first be premixed, for example ina dry blender. This preblend may then be fused and fluxed while working at elevated (e.g. 320-400F., preferably 330"-360F.), for example in an internal mixer such as a Banburymixer, or on an open roll mill. If desired the polymers may be mixed --in an extruder.
