Summary
The polar electron-deficient alkene methyl acrylate was readily polymerised in good yield by the CpTiCl3-MAO system to give a polymer with a relatively low molecular weight, but reasonable polydispersity. The polymer appears to be atactic. The same system also gave a random sequence 1:1 copolymer of methyl acrylate and styrene, which according to NMR and SEM studies was a true copolymer rather than a blend.

Qian M, Bala D, Yousaf M, Zhang H, Huang J, Sun J, Liang C (2002) J Mol Cat A: Chemical 188:1 notes a cationic polymerisation of methyl methacrylate by an allylcyclopentadienyl lanthanide, but no MAO was needed. In the CpTiCl3-MAO system described by us here, no polymerisation was observed in the absence of MAO. There was some polymerisation with MAO in the absence of CpTiCl3, but the 1 h yield was < 4% compared with the 1 h yield of >15% when CpTiCl3 was present.
