of the corresponding alkaline agent in available water the rest of m w is used to prepare the biopolymer solution called u201c sol b u201d to a kneader equipped with a heating cooling mantle a quantity of synthetic polymer m a and sol c are mixed at a temperature not less than 20 u00b0 c and not greater than 90 u00b0 c in another embodiment the temperature is between 40 u00b0 c and 70 u00b0 c for not less than 1 hour and not greater than 4 hours in another embodiment the period of time is between 2 hours and 3 hours sol b pre heated at temperature of 50 u00b0 c is added to the mixture the mixing continues at the same temperature for an interval of time not less than 1 hour and not more than 4 hours in another embodiment the time is between 2 and 3 hours abc sol is obtained as a mixture in the form of a viscous fluid with a consistency similar to a polymeric melt abc sol from above is cooled at a temperature not less than 15 u00b0 c and not greater than 55 u00b0 c in another embodiment the temperature is between 25 u00b0 c and 45 u00b0 c the viscous fluid is removed from kneader by extrusion through a stainless steal holed plate with holes having a diameter not less than 2 mm and not greater than 10 mm in another embodiment the holes are between 4 mm and 8 mm the cylindrical shaped material is generally not less than 5.
