Abstract: A process for activating polymer including preconditioning a diluent by heating it to a high temperature and then mixing the heated diluent with the polymer to form a blend having a high polymer content (e.g., about 5% polymer and 95% hot diluent). The blend is activated and then diluted by mixing it with a cold or cool diluent in order to provide an output stream of about 0.25-2% polymer having a relatively low temperature. The high temperature and high polymer content enables a continuous process, as distinguished from batch processes used heretofore which required substantial holding time in an aging tank. The reduction of the temperature of the blend by mixing it with cold or cool diluent prevents damage to heat-sensitive polymers.

Abstract: Fibrous network structures are produced within liquid polymer resins by passing the fiber-containing resin along a channel having a plurality of sets of flow modifying elements which establish a regulated succession of velocity profiles for the principal flow direction and the two directions perpendicular thereto. The individual velocity profiles persist over distances which are small compared to the channel dimension over which they are established and are such that there is substantially no net deviation from the principal flow direction. The velocity profiles superimpose on each other to cause rotation and sliding of the fibers so that a coherent network structure is built up which persists through extrusion dies and molds into the solid state. By means of a large number of touches per fiber the structures thereby established confer efficient mechanical reinforcing properties and enhanced thermal properties on the polymer composition.
