【Abstract】 Tri-n-butyltin methacrylate monomer was prepared and copolymerized under the influence of free radical initiators, with several vinyl monomers. By means of analytical YBR method, the reactivity ratios of three pairs of monomers were determined for solving of fhe differentical form of copolymer equation. In the copolymerization of tri-n-butyltin metbacrylate（M₁）with methyl methacrylate （M₂）, the reactivity ratios were found to be r₁= 0.515 ±0.061,r₂ = 0.669±0.071; with styrene （M₂） they were r₁= 0.328 ±0.028, r₂= 1.203 ± 0.050; with methyacrylate （M₂） they were r₁=-1.013 + 0.055, r₂= 0.288 ±0.032. Taking the individual Q, e Values of particular monomer; Q. e Values in copolymerization can be obtained through average, for tri-n-butyltin methacrylate monomer the Values of Q = 0.622, e = 0.329.更多还原
