Abstract
Copolymerization of 4-vinyl-1,4-butyrolactone (1) and cyanoethylene (2) initiated by 2,2′-azobisisobutyronitrile were carried out. The following reactivity ratios were found for the bulk copolymerization at 50°C for 1, r1=0.004, and for 2, r2=4.4. Radical reactivity indices and frontier electron densities for 1, 2, and 3-vinyl-1,4-butyrolactone were calculated.
