Fix request[edit]

Hi, don't have time now, but would be good to include reference to original paper: Chiefari J, Chong YK, Ercole F, Krstina J, Jeffery J, Le TPT, Mayadunne RTA, Meijs GF, Moad CL, Moad G, Rizzardo E, Thang SH MACROMOLECULES 31 (16): 5559-5562 AUG 11 1998

* Done! It still needs a mechanism etc., though. Dflanagan 17:27, 25 March 2006 (UTC)

jetaxe No worries I added a mechanism i whipped up in chemdraw...

The Wikimedia Foundation information team has received a complaint from the originator of that scheme, specifically that it was copied without permission. Copyright is very important to Wikipedia, so I have removed the mechanism. Please be careful not to violate copyright when adding material to Wikipedia. FreplySpang (talk) 21:16, 7 May 2006 (UTC)

  • The mechanism was not completely correct and I have replaced it with one that I have drawn from scratch. AussieScientist (talk) 19:14, 4 January 2012 (UTC)

Perhaps a rather minor point I feel, but would it not be better to move this page to Reversible Addition-Fragmentation Chain Transfer and have this page a redirect there? I just feel that having the full name generally looks better on a page, rather than a first-line explanation of the abbreviation. The same would be true of ATRP_(chemistry), I'm sure there would be others but these are the two I've noticed so far. Mothball (talk) 12:33, 14 October 2009 (UTC)

I somewhat agree. Is there a discussion page where such things can be determined. I think it would be best if the different methods were named after the common abbreviation, eg. RAFT-page is Reversible Addition-Fragmentation chain Transfer. (talk) 20:24, 22 June 2011 (UTC)

Citing: "Using a multifuntional CTA can..." What is a CTA??? No link nor any wiki entry within chemistry on that. Unless its Cellulosetriacetate, which I would find strange. (talk) 20:24, 22 June 2011 (UTC)

  • Done. This has been clarified in a number of my edits. AussieScientist (talk) 19:14, 4 January 2012 (UTC)

Figure 3 uses methacrylic acid in the second reaction scheme, and then yields polyacrylic acid as a product. — Preceding unsigned comment added by Dikbrown (talkcontribs) 22:57, 8 April 2012 (UTC)

Page cleanup[edit]

I've noticed a week or so ago that this page contained false and misleading information and has typographical errors. I intend to invest some time working on this page. In particular the section on the Mechanism contains false information and the Applications section seems confusing to me. Suggestions on my edits, as they appear are welcome. AussieScientist (talk) 20:52, 3 January 2012 (UTC)

Update: I have begun making these corrections / additions. AussieScientist (talk) 20:52, 3 January 2012 (UTC)

In figure 4 of the article the name of the first substance in the second row is methacrylac acide not acrylic acide — Preceding unsigned comment added by (talk) 01:39, 3 September 2011 (UTC)

  • This is true, but I don't have the source to edit this image. Actually, I question the benefit of this image in explaining the RAFT process. Maybe I'll remove it at some point. AussieScientist (talk) 15:48, 29 January 2012 (UTC)

Figure 2[edit]

There is a picture labeled "figure 2" with this caption: Figure 2. Two examples of RAFT agents. The picture shows chemical structure and two chemicals in bottles. What are these chemicals? Can the names be provided, or are they strange chemicals with no common name? Blue Rasberry (talk) 19:34, 29 January 2012 (UTC)

  • Looking at the labels, CPADB must be (4-cyanopentanoic acid)-4-dithiobenzoate and I don't have time right now to find out the other one. I believe they correspond to the structures on the left. I question the use of these pictures. What do you think? They are just two coloured bits of stuff in jars... (talk) 21:20, 7 February 2012 (UTC)
