OF MODEL OXAZOLIDONE COMPOUNDS FROM FATTY EPOXIDES AND ISOCYANATES

Polymers from renewable resources have great economical, ecological and technical significance. Vegetable oils are potentially very useful raw materials for the synthesis of different polymeric materials but they should be chemically transformed to contain some reactive groups. One of the ways is the formation of oxazolidone prepolymers with terminal isocyanate groups by reacting epoxidized vegetable oils with an excess of diisocyanate.
In order to examine the reactivity of internal epoxides in the long aliphatic chains, the oxazolidone formation from 9,10-epoxyoctadecane and phenyl isocyanate was studied. 9,10-epoxyoctadecane corresponds to the one branch of epoxidized vegetable oil with one epoxy group per chain. Lithium chloride, aluminum trichloride, zinc iodide, aluminum triisopropoxide, triphenylantimony tetraiodide and imidazole were tested as potential catalysts. The syntheses were carried out in boiling dimethylformamide. The reaction product was separated from the reaction mixture and analyzed by FTIR, NMR, GPC and DSC.
so generally from the first eye wiev as a component of speciffic catalytic compositions
