high shear twin screw reactor additional p 2 o 5 is added to the mixture to maintain the effective concentration of ppa at about 82 the temperature is then gradually increased to 150 u00b0 c for about 24 hours dependant on the effectiveness of mixing stirring in the reactor or until the mixture becomes smoothly homogeneous stir opalescence should be observed regardless of the polymerization process utilized the resultant liquid crystalline solution also called u201c dope u201d can be shaped through a spinneret or film die followed by coagulation of the shaped solution in a coagulation bath using compositions and coagulation rates known in the art alternatively the shaped solution can be consolidated in a forced air oven or a vacuum oven at the appropriate temperature to evaporate the solvent as will be appreciated by those having ordinary skill in the art there is an air gap between the exit of the spinneret or the shaping die and the top surface of the coagulation bath further the speed of the take up roll drum is higher than the linear extrusion rate of the polymer solution the ratio between the take up speed and the extrusion rate is referred to as the spin draw ratio sdr and it is preferred that the sdr be as high as possible e g at least about 2 and preferably from about 3 to about 150 for the greatest possible.
