PROCESS FOR PREPARING COMPOUNDS CONTAINING ISOCYANURIC GROUPS BY CATALYTIC CYCLOTRIMERIZATION OF ISOCYANATES IN THE PRESENCE OF AMINO SILYL- ISOCYANURATES GROUPS CONTAINING COMPOUNDS PRODUCED IN THE PROCESS

摘要

ABSTRACT OF THE DISCLOSURE: The present invention relates to a method obtaining compounds containing isocyanuric groups by cyclotrimerization monomeric or polymeric isocyanate cata-lytic. It is characterized in that is used as the compound initiating the reaction, an aminosilyl group compound selected from monoaminosilanes, the diamino the silylureas and silazanes. This catalytic system is very effective to cyclotrimerize aliphatic isocyanates, cycloaliphatic and allows to obtain particularly polyisocyanurates polyisocyanates.
