✦ Synopsis
Polymerizations of methyl methacrylate (MMA), vinyl acetate, acrylonitrile or styrene (St) initiated by methyl derivatives of Ti(IV) are consistent with a radical process. This conclusion is supported by tacticities of the resulting polymers which are close to those for conventional radical samples and show that propagation obeys a Bernoullian statistics. The major evidence is provided by statistical MMA-St copolymerization which clearly exhibits radical reactivity ratios.
