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. PIBCH2CH2CH2OH 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. 1H and 13C 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.
