| description | A process for producing a precursor material comprising the steps of, agitating a polymer material and a fibre material in a blending device comprising a blending means operating at a velocity sufficient to bring about an increase of the temperature to at least a temperature beyond the VI CAT softening point or within or beyond the melting temperature range of the polymer material. Thereafter, maintaining the velocity of the blending means and, when the specific motor power needed to maintain the velocity of the blending means increases by a predetermined amount or reaches a predetermined value, reducing the velocity. Repeating the previous step as necessary, until the velocity falls below a first threshold value to form an intermediate material. Finally, comminuting the formed intermediate material in a comminuting device comprising a comminuting means operating at a velocity allowing a decrease in temperature, until the temperature falls below a second threshold value. |
