Popis: Hydrogenated nitrile rubber (Therban) was modified in the solution and in the melt to introduce oxazoline units into the chain. Conversion of nitrile groups reached about 40% what corresponds 13.6 mol% of oxazoline units in the modified sample. The chemical structure of product was confirmed by FTIR and 2D NMR spectra. To calculate the degree of conversion from IR spectra, correlation between 1 H NMR and IR data was found. Blends of modified samples with polyamide-6 were prepared. DSC data seem to indicate the partial miscibility of blend components as a result of the creation of covalent bonds between them. By addition of modified rubber, impact strength of the polyamide was highly improved.
