Transformation of RAFT Polymer End Groups

Problem 11.25 Discuss a reaction protocol for the synthesis of a well-de ned polystyrene with one end having a primary amine end group, H-[-CH(C6Hs)CH2-]n-NH2, through the use of RAFT techniques.

Also, various end functional groups have been introduced by transformation of RAFT polymer end groups or by the use of functionaUzed initiators [113-116], and the influence of these end groups has been examined in detail [115]. Furthermore, the following groups were attached to one or both ends of PNIPAM, as shown in Fig. 6 pyrenyl groups (27) for fluorescent...
