MANUFACTURE OF BLOCKED POLYISOCYANATE HAVING CARBODIIMIDO GROUP, POLYSOCYANATE THEREBY AND USE FOR MANUFACTURE OF PLASTIC

1. A process for the production of organic compounds containing (i) carbodiimide and/or uretone imine groups and (ii) blocked isocyanate groups, characterized in that from 30 to 70% of the isocyanate groups of an organic polyisocyanate having a molecular weight of 174 to 1 000 and containing only ar...

Beschreibung
Zusammenfassung:	1. A process for the production of organic compounds containing (i) carbodiimide and/or uretone imine groups and (ii) blocked isocyanate groups, characterized in that from 30 to 70% of the isocyanate groups of an organic polyisocyanate having a molecular weight of 174 to 1 000 and containing only aromatically bound isocyanate groups are blocked by reaction with a monofunctional blocking agent for isocyanate groups, after which from 65 to 100% of the free isocyanate groups still remaining are converted into carbodiimide groups with elimination of carbon dioxide.
