DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Polymns. of Bu acrylate (BA), Me methacrylate (MMA) and styrene (St) were promoted by the Ru(II) cyclometalated complex with labile MeCN ligand in the presence of Al(OiPr)3. The polymn. proceeds via radical mechanism and requires the loss of MeCN ligand. The poor control over the polymns. 2397-67-3 and 5445-17-0 which are cas registry numbers of chemicals are mentioned. can be explained in terms of the traditional ATRP scheme. However, the controllability may be significantly improved by addn. of reducing SnCl2. Mechanism of the process is proposed. .
