APPLICATION: US 2002-195971 16 Jul 2002. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) A process for polymn. of vinyl monomers is described comprising polymg. vinyl monomers in the presence of an initiating system comprising (i) an org. iodide, org. bromide, org. chloride, or an org. 1617-17-0 and 10377-51-2 are cas registry numbers of chemicals which are used as reagents here. sulfur initiator compd., and (ii) a layered material catalyst, and wherein when the initiator compd. comprises an org. bromide or org. chloride compd., the initiating system further comprises an iodide or sulfur contg. salt compd. or a transition metal salt. The present invention provides a novel method for living polymn. of vinyl monomers, which provides a high level of macromol. control over the polymn. process and which leads to uniform and controllable polymeric products, which may include well-defined structures and complex architectures. .
