Solution copolymerization of alkyl methacrylates andN–vinyl carbazole: Reactivity ratios

摘要

AbstractThe copolymerization of ethyl methacrylate andn‐butyl methacrylate withN‐vinyl carbazole was studied at 60°C, using AIBN as the initiator. The reactivity ratios of the monomers were determined in benzene, ethyl acetate, acetone or (N,N–dimethylformamide) solutions. The values ofr1andr2were calculated by the Fineman–Ross and Kelen–Tüdös methods and were compared with those obtained earlier in bulk copo
