The copolymerization of tri-n-butyl tin acrylate (TBTA) with methylmethacrylate (MMA) has been investigated in dioxane. The composition of these copolymers was determined quantitatively by 1a nuclear magnetic resonance (NMR) spectroscopy. The tin contents were estimated by gravimetric as well as the
Copolymers of N-vinylcarbazole (NVC) and N,N-dimethylaminoethyl methacrylate (DMAEMA) were prepared by free-radical polymerization in a toluene solution at 60ะC using 2,2 -azobisisobutyronitrile (AIBN) as an initiator. The reactivity ratios of both monomers were calculated using the extended Kelen-T
