Notizen:
The polymerizations of trimethylvinyltin (TMSnV) and tributylvinyltin (TBSnV) were carried out with the use of γ-ray, radical, or ionic initiators. These monomers did not undergo the polymerization by themselves, but they did copolymerize with styrene (St) or methyl methacrylate (MMA) when a radical initiator was used. From the results obtained by the copolymerization, monomer reactivity ratios and Q-e values were obtained as follows: for the system St(M1)—TMSnV, r1 = 44.8, r2 = 0.001, Q2 = 0.005, e2 = 0.962; for the system MMA (M1)—TMSnV, r1 = 25.1, r2 = 0.03, Q2 = 0.036, e2 = 0.933; for the system St(M1)—TBSnV, r1 = 16.0, r2 = 0.005, Q2 = 0.017, e2 = 0.822; for the system MMA(M1)—TBSnV, r1 = 27.9, r2 = 0.03, Q2 = 0.031, e2 = 0.822. The abilities of TMSnV and TBSnV to polymerize are discussed on the basis of the Q and e values obtained.
