Homopolymers of 2-isocyanatoethyl methacrylate, ethyl alpha-cyanoacrylate, and ethyl alpha-isocyanatoacrylate were prepared in tetrahydrofuran at 22 to 25 degrees C using tri-n-butylborane oxide as a free radical initiator. Additionally, ethyl alpha-isocyanatoacrylate was homopolymerized using 2,2’-azobis(2-methylbutyronitrile) as the initiator. Homopolymers were characterized by photoacoustic FT-IR, DSC, and elemental analysis.
