| Abstract: | Polybutadiene has been modified with ?-caprolacton during butadiene polymerization carried out in the presence of catalytic systems based on neodymium and organoaluminum compounds at a butadiene conversion of 90–96%. The structure, phase state, and temperature behavior of polybutadienes modified with ?-caprolacton have been studied by IR and 13C NMR spectroscopy, DSC, and X-ray diffraction analysis. The above approach shows promise for the synthesis of new-generation elastomers which do not rank below conventional rubbers in terms of their characteristics but possess biodegradability. |
