Interaction of butadiene-nitrile rubber with phenol-formaldehyde resins of random-structure
A technique for vulcanization of nitrile butadiene rubber with low-molecular-weight phenol-formaldehyde resins of random structure has been developed. The correctness of the technique was confirmed by 13С NMR data, simultaneous thermal analysis and differential scanning calorimetry and thermomechanical analysis of the obtained samples and initial components. It is shown that the obtained samples have higher physical and mechanical characteristics in comparison with the original rubber.
