Abstract
In this communication we provide the most recent results on RAFT-mediated ring-closing polymerization of diallyldimethylammonium chloride (DADMAC) The polymerization was carried out in aqueous solution employing 2 2`-azobis(2-methylpropionamidine)-dihydrochloride as the free radical initiator and trithiocarbonate RAFI' agent (2-{[(dodecylsulfanyl)carbonothioyl sulfanyl]}propanoic acid DoPAT) as the controlling RAFT agent The results show that - while the system is not as completely controlled as previously described - it is nevertheless possible to mediate the polymerization of DADMAC and impart some living characteristics onto the system The initial study on the RAFT-mediated polymerization of DADMAC may have overestimated the degree of livingness within this reaction However it is possible - at low conversions - for some living characteristics to be observed as the evolution of molecular weight with conversion is linear In addition polymers with a reasonably narrow polydispersity can be Isolated (c) 2010 Elsevier Ltd All rights reserved
