Title: | The effect of Z-group modification on the RAFT polymerization of N-vinylpyrrolidone controlled by "switchable" N-pyridyl-functional dithiocarbamates | Contributor(s): | Stace, Sarah J (author); Moad, Graeme (author); Fellows, Chris (author) ; Keddie, Daniel (author) | Publication Date: | 2015 | DOI: | 10.1039/c5py01021g | Handle Link: | https://hdl.handle.net/1959.11/18361 | Abstract: | The ability of a RAFT agent to control the polymerization of a monomer is dictated by the structures of both the monomer and the RAFT agent. In this paper, the polymerization of N-vinylpyrrolidone was examined with a series of cyanomethyl N-aryl-N-pyridyldithiocarbamates [(4-R'Ph)N(py)C(=S)SCH₂CN] varying in the substituent (R') at the 4-position on the phenyl ring. The polymerization of N-vinylpyrrolidone was best controlled when R' was methoxy; one of the least active RAFT agents in the series. The preservation of RAFT agent functionality was demonstrated by chain extension experiments with further N-vinylpyrrolidone. Again best control again was found for the RAFT agent with R' = MeOPh. The utility of this RAFT agent was also proved with the preparation of poly(N-isopropylacrylamide)-block-poly(Nvinylpyrrolidone). | Publication Type: | Journal Article | Source of Publication: | Polymer Chemistry, 6(40), p. 7119-7126 | Publisher: | Royal Society of Chemistry | Place of Publication: | United Kingdom | ISSN: | 1759-9962 1759-9954 |
