Abstract:
The use of reversible addition–fragmentation chain transfer (RAFT) polymerisation for the production of DNA–polymer conjugates is explored. Chapter 1 gives a general introduction to the field of DNA–polymer conjugates, their potential applications and methods for their synthesis. The need for a general, solutionphase technique for DNA–polymer conjugation is highlighted. In Chapters 2-5, the use of a number of different strategies for the production of DNA–polymer conjugates is described. Amide coupling (Chapter 2) is found to produce the desired products only under very specific reaction condi

Abstract:
Thesis (MSc (Chemistry and Polymer Science))--University of Stellenbosch, 2009.<br>ENGLISH ABSTRACT: In this study, a functional styrene – maleic anhydride copolymer (SMA) was synthesized via reversible addition-fragmentation chain transfer mediated polymerization (RAFT). The obtained copolymer had an alternating structure with well controlled molecular weight. The structure of the copolymer was found to alternating when characterized by NMR and MALDI-Tof-MS. SMA copolymer is functional polymer due to the presence of reactive maleic anhydride moiety in its backbone. The SMA copolymer wa
