Abstract
Methacrylate‐terminated polyisobutylenes (PIB‐MAs) were synthesized by transesterification of vinyl methacrylate by hydroxyl‐terminated polyisobutylenes (PIB‐OH) using Candida antarctica lipase B (Novozyme 435) catalyst in hexane at 50 °C. PIBCH~2~CH~2~CH~2~OH and GlissopalOH, synthesized by anti‐Markovnikov hydrobromination of allyl‐terminated PIB and Glissopal®2300 followed by hydrolysis, were quantitatively converted into the corresponding PIB‐MAs. ^1^H and ^13^C NMR spectroscopy verified the formation of the expected structures. This “green” chemistry is a very promising methodology for polymer functionalization in general, and biomaterial synthesis in particular.
