| titleOfInvention | Method for producing thermoplastic polyoxazolidinone |
| abstract | copolymerization of a diisocyanate compound (A) and a bisepoxide compound (B) in the presence of a catalyst (C) and compound (D), optionally in a solvent (E), wherein compound (D) is a monofunctional isocyanate, a monofunctional at least one compound selected from the group consisting of epoxides, cyclic carbonates, monofunctional alcohols, monofunctional amines, preferably monofunctional epoxides, wherein the process is ≥ 178 °C to ≤ 230 °C, preferably ≥ 182 °C to ≤ 220 °C, more preferably ≥ 188 °C to ≤ 210 °C; Most preferably it is carried out at a reaction temperature of ≥ 190 ° C to ≤ 205 ° C, wherein the bisepoxide compound (B) is 2,4'-isopropylidenediphenol diglycidyl ether (2,4' BADGE) and 4,4'-isopropylidenediphenol diglycidyl ether (4,4' BADGE); wherein the molar ratio of 2,4'-isopropylidenediphenol diglycidyl ether (2,4' BADGE) is 2,4'-isopropylidenediphenol diglycidyl ether (2,4' BADGE) and 4 , ≥3 mol% to ≤11 mol%, preferably ≥4 mol% to ≤9 mol%, more preferably ≥4 mol% to ≤9 mol%, relative to the sum of 4'-isopropylidenediphenol diglycidyl ether (4,4' BADGE) Process for the production of thermoplastic polyoxazolidinones preferably ≥5 mol% to ≤8 mol%. The present invention also relates to the resulting thermoplastic polyoxazolidinone. |
