METHOD FOR THE PRODUCTION OF EPOXY-GROUP TERMINATED POLYOXAZOLIDINONES
The invention is related to a process for producing an epoxy-group terminated polyoxazolidinone comprising the copolymerization of a polyisocyanate compound (A) with two or more isocyanate groups with a polyepoxide compound (B) with two or more epoxy groups in the presence of a specific catalyst (C)...

| description | The invention is related to a process for producing an epoxy-group terminated polyoxazolidinone comprising the copolymerization of a polyisocyanate compound (A) with two or more isocyanate groups with a polyepoxide compound (B) with two or more epoxy groups in the presence of a specific catalyst (C), wherein the molar ratio of the epoxy groups of the polyepoxide compound (B) to the isocyanate groups of the polyisocyanate compound (A) is larger than 2:1 and less than 25:1, and wherein the copolymerization is operated in the absence of an additional solvent (D-1) with an boiling point higher than 170 °C, preferred, 165 °C, more preferred 160°C most preferred 150 °C at 1 bar (absolute). The invention is also related to the resulting epoxy-group terminated polyoxazolidinones. |
