Description

The r-ray-induced copolymerization of vinylphosphonyl dichloride (VPDC) with acrylonitrile (AN) was studied at 25 and -78°C, and the reaction mechanism was examined. The copolymerization proceeded by a free radical mechanism at 25°C, and the following reactivity ratios Q1 and e1 value for VPDC monomer (M1) were estimated.r1=0.05, r2=6.0Q1=0.87, e1=2.7On the other hand, the rate of copolymerization has a maximum point at about 30 mol% of VPDC monomer concentration at -78°C. In the Fineman-Ross diagram, the r1 took a negative value, and moreover, the points shifted from the linear relation in the region from 70 to 0 mol% of VPDC monomer concentration.
