Polybutadiene of low cis ‐content was modified with the precursors of nitrones and nitrile oxide. The carbon‐black‐filled vulcanizates of the modified rubbers containing isoxazolidine and isoxazoline groups showed good tensile properties. The effect of modification was ascribed to the interaction between active sites of carbon black particles and the heterorings.
