Polybutadiene was depolymerized using ethyl acrylate. With these conditions, pressure manipulation, homo-metathesis byproduct, and additional solvent are eliminated. Moreover, the new ester functionality allows further synthetic manipulation. The use of copper iodide as an additive was investigated and was shown to significantly stabilize Grubbs second generation catalyst, even in the presence of air. Finally, an unsaturated polyamide was synthesized by depolymerizing polybutadiene with acryloyl chloride and polymerizing the resultant product with 1,6-diaminohexane.
