Preparation of isocyanate-terminated urethane group-containing prepolymers |
| abstract |
The invention relates to a process for preparing isocyanate-terminated prepolymers containing urethane groups, comprising reacting a reaction mixture containing a stoichiometric excess of at least one aliphatic and/or cycloaliphatic diisocyanate and a polyol composition with an OH number> 400, characterized in that the reaction mixture with a specific Power input in the range of 0.5 kW / m3 to 40 kW / m 3 , based on the total volume of the reaction mixture, is mixed. |
