Modification of polybutadiene with caprolacton during polymerization
- 44 Downloads
Polybutadiene has been modified with ɛ-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 ɛ-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.
