| titleOfInvention |
Process for the preparation of highfunctionality aromatic polyisocyanates |
| abstract |
The invention relates to a method for producingnhighly functional aromatic polyisocyanates by reactionnof aromatic polyisocyanates, optionally in a mixture withnfurther mono- and / or polyisocyanates, catalytically with the additionnacting acidic substances and water, which is characterizednis that as aromatic polyisocyanates at least onenToluene diisocyanate and as a catalytic acidic substancenat least one alkyl and / or aralkyl phosphate can be usednand you do the procedure so that the addition of waternwith a temperature / time gradient increase of 5 to 60 ° / hournup to the setting of an isocyanate modification degree ofnStarting NCO end groups from 1 to 80%.n n n The invention furthermore relates to those using this methodnproduced highly functional aromatic polyisocyanatesnitself and its use for the production of polyurethane foams,nespecially flexible polyurethane foams. |
