Method for preparing carbodiimide |
| abstract |
The present invention relates to a method for preparing a polycarbodiimide, which comprises (i) preparing a reaction mixture comprising a diisocyanate and a catalyst, and (ii) in a stirred tank by a range of 20 to 800 mbar. The diisocyanate is polymerized under pressure to heat the reaction mixture prepared in (i) to a temperature in the range of 20 to 250 ° C to form the polycarbodiimide, wherein a stirrer device is used to agitate the polymer during the polymerization. Reaction mixture, The method includes axially transferring the reaction mixture to the axis of rotation of the stirring operation by means of the stirring operation. |
