1. A method for the production of polyoxazolidinone compounds, comprising reacting an isocyanate compound with an epoxide compound in the presence of a catalyst,
wherein the catalyst corresponds to the general formula (I):
[E(R1)(R2)(R3)(R4)]+nXn− (I) wherein: E represents a P, As, Sb and/or Bi, n represents 1, 2 or 3,
wherein:when n=1, X− represents F−, Cl−, OH−, CR3CO2−, NO2−, NO3−, ClO−, ClO2−, ClO3−, ClO4−, OR− wherein in which R represents a linear or branched alkyl group comprising 1 to 22 carbon atoms, a cycloaliphatic group comprising 3 to 22 carbon atoms or an aryl group comprising 6 to 18 carbon atoms, N3*, NH2* and/or SCN;when n=2, X2− represents SO42−, CO32− and/or S2O32−; and when n=3, X3− is represents PO43−; and (R1), 2), (R3), (R4) are independently of one another selected from the group consisting of linear or branched alkyl groups comprising 1 to 22 carbon atoms, which are optionally substituted with heteroatoms and/or heteroatom comprising substituents, cycloaliphatic groups comprising 3 to 22 carbon atoms, which are optionally substituted with heteroatoms and/or heteroatom comprising substituents, C1 to C3 alkyl-bridged cycloaliphatic groups comprising 3 to 22 carbon atoms, which are optionally substituted with heteroatoms and/or heteroatom containing substituents and aryl groups comprising 6 to 18 carbon atoms, which are optionally substituted with alkyl groups comprising 1 to 10 carbon atoms and/or heteroatoms. |
