Polyisobutylene-based thermoplastic elastomers, AIBA {poly(alloocimene-b-isobutylene-b-alloocimene) triblocks), synthesized by carbocationic polymerization were electrospun into free-standing rubbery fiber mats from THF/Toluene solvent mixtures. The tensile strength measured on microdumbbells was 2.7 MPa at 520% elongation at break. Cell culture studies have shown these rubbery fiber mats to be non-cytotoxic. Electrospinning from non-flammable chloroform was also successful. Due to excellent biocompatibility and thermoplastic elastomeric properties, these fiber mats hold great promise for drug-eluting implant cover applications.
