CHARACTERIZATION OF POLY(METHYL METHACRYLATE-co-TRI-n-BUTYLTIN METHACRYLATE) BY 13C- AND 119Sn-NMR

Methyl methacrylate(MMA)-tri-n-bythyltin methacrylate (TBTMA) copolymers were prepared by polymerization using benzyl peroxide as an initiator. 13 C-NMR spectra for carbonyl carbon of the copolymers indicate both of configurational and compositional sequences. Moreover, 119 Sn-NMR chemical shifts depend on compositional sequence
