“…[302] Bivigou-Koumba et al [286] reported that strong retardation was observed in extending PSt macro-RAFT agents with N-isopropylacrylamide (NIPAM), whereas chain extension of PNIPAM macro-RAFT with St was successful. In both cases slow initiation by the macro-RAFT agent-derived propagating species was suggested as a possible explanation.…”

This paper provides a second update to the review of reversible deactivation radical polymerization achieved with thiocarbonylthio compounds (ZC(=S)SR) by a mechanism of reversible addition-fragmentation chain transfer (RAFT) that was published in June 2005 (Aust. J. Chem. 2005, 58, 379-410). The first update was published in November 2006 (Aust. J. Chem. 2006, 59, 669-692). This review cites over 500 papers that appeared during the period mid-2006 to mid-2009 covering various aspects of RAFT polymerization ranging from reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses and a diverse range of applications. Significant developments have occurred, particularly in the areas of novel RAFT agents, techniques for end-group removal and transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.

Diblock and triblock copolymers of poly-L-lactide (PLLA) and polystyrene (PS) were synthesized and the mechanical properties of these copolymers studied. Free radical polymerization of styrene in the presence of 2-mercaptoethanol as functional chain transfer agent produced mono-functionalized PS-blocks which were used as macroinitiators in the subsequent ring opening polymerization (ROP) of L-lactide to produce the diblock copolymers. Furthermore a a-x-bishydroxyl functionalized PS-block was synthesized by RAFT, which was then engaged as bifunctional initiator for the ROP of L-lactide to provide the triblock copolymers PLLA-PS-PLLA. Through the copolymerisation and high molar masses, it was possible to achieve an improved mechanical property profile, compared with pure PLLA, or the analogous blends of PLLA and PS. A weight fraction of PS of 10-30% was found to be the optimal range for improving the heat deflection temperature (HDT), as well as mechanical properties such as ultimate tensile strength or elongation at break.
