Modified aromatic polyisocyanates and their use for the production of rigid foamed materials

Modified aromatic polyisocyanates and their use for the production of rigid foamed materials

Polyaromatic polyisocyanates are modified by reaction with 0.1 to 10 weight %, preferably 2 to 7 weight % (based on polyisocyanate) of a polyether alcohol of molecular weight 206 to 948, obtainable by the reaction of alkylene oxides with C6-C30, preferably C8-C20, hydrocarbons containing 1 to 3 acti...

Zusammenfassung:Polyaromatic polyisocyanates are modified by reaction with 0.1 to 10 weight %, preferably 2 to 7 weight % (based on polyisocyanate) of a polyether alcohol of molecular weight 206 to 948, obtainable by the reaction of alkylene oxides with C6-C30, preferably C8-C20, hydrocarbons containing 1 to 3 active H atoms, and are used for the production of rigid polyurethane foamed materials.
