| titleOfInvention | Trimerization of isocyanates |
| abstract | R2-C(-R1)(-R3)-CO-CO-CH(-R4)-R5 WHEREIN R1 AND R4 ARE INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL GROUPS HAVING FROM 1 TO 4 CARBON ATOMS, AND ARYL GROUPS, R2, R3, AND R5 ARE INDEPENDENTLY SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND ALKYL GROUPS HAVING FROM 1 TO 4 CARBON ATOMS, AND THE TOTAL NUMBER OF CARBON ATOMS IN THE ALKYL GROUP IS FROM 1 TO 10. THE REACTION IS DIVIDED INTO TWO STAGES. THE FIRST STAGE IS AN INITIATION PERIOD DURING WHICH SUBSTANTIALLY NO POLYMERIZATION OCCURS. THE SECOND STATE IS THE RAPID TRIMERIZATION OF THE ISOCYANATE. AROMATIC ISOCYANATES ARE TRIMERIZED WITH A CATALYST SYSTEM WHICH COMPRISES A MIXTURE OF AT LEAST ONE TERTIARY AMINE AND AT LEAST ONE CO-CATALYST SELECTED FROM THE GROUP CONSISTING OF BENZOYL PEROXIDE AND COMPOUNDS HAVING THE FORMULA |
