| titleOfInvention | Process for incorporating solids to produce thermally sensitive polymers in a planetary roller extruder |
| abstract | The invention relates to a process for the preparation of thermally crosslinkable polymers in a planetary roller extruder, wherein a) the planetary roller extruder comprises a filling part and a compounding part, which is formed by a roll cylinder region which consists of at least two, preferably at least three coupled roll cylinders whose planetary spindles are driven by a single common central spindle, b) the polymers are fed to the planetary roller extruder in a plasticized state, c) the plasticized polymers are fed into the first roll cylinder, namely within the first half of the first roll cylinder, d) the filling part of the planetary roller extruder is subjected to a vacuum, e) if the roll cylinder region is formed from two roll cylinders, the shell of the second roll cylinder has an opening through which the plasticized polymers are freed from air and optionally further volatile components by means of a vacuum, or if the roll cylinder region is formed from more than two roll cylinders, the jacket of the second roll cylinder of the at least three roll cylinders or the jacket of a downstream subsequent roll cylinder has an opening via which the plasticized polymers are freed from air and optionally further volatile components by means of a vacuum, f) the flow temperatures of the central spindle and the at least two roll cylinders under vacuum are set so that the polymers to be degassed remain in the plastic state, g) downstream of the degassing by vacuum the plasticized polymers one or more liquids such as thermal crosslinkers, crosslinking accelerators, dye solutions or dye dispersions are preferably metered continuously, ie in the second roll cylinder or in one or more of the optionally present roll cylinders or in the intermediate rings between the second and third roll cylinder or between third and fourth roll cylinder, etc., h) the mixture of plasticized polymers and liquids in the roll cylinder region, in which the liquids are incorporated into the plasticized polymers are cooled so that after the exit of the mixture from the planetary roller extruder no evaporation of the plasticized in the polymers preferably homogeneously mixed liquids . i) the length of the roll cylinder region in which degassing of the plasticized polymers takes place by means of vacuum is between more than 50% and 80%, preferably between 60% and 70%, of the length of the entire roll cylinder region, j) the mixture of plasticized polymers and modifying liquids is preferably supplied to a coating unit without further additional treatment, more preferably inline, that is to say without intermediate filling or transfer with subsequent remelting. |
