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.
