Joe's Peer Review
Greetings,

Article is looking good thus far. I have a couple of suggestions. The introduction contains many of the applications associated with Nylon 11, this makes having an application section redundant. I also suggest re-wording parts of the introduction, as some of it is fragmented. The history section effectively depicts how Nylon 11 was discovered. I would suggest linking more of the people mentioned in this section to other pages on Wikipedia. The chemistry section in concise, perhaps a little more information is needed. When it comes time for adding media, I would recommend trying to find images of the molecular structure of Nylon 11, as well as media showing the process of creating it.

Joe,

I was thinking the same thing in terms of the applications. I am going to remove the applications from the summary and create a new section, as I have found a number of additional applications and it would give me some space to explain why nylon 11 is used for each of the applications. The introduction was the only section included in the original article, so i did not write it. It does bug me a bit how "choppy" it is, however it does effectively describe nylon 11 almost perfectly for a quick summary. I sat staring at it for a good amount of time and could not think of much to add, however I'll give another look at it. I'll go through and try to see if any of the names that came up in the history have their own wikipedia pages. A lot of those names were tough to find on google, let alone wikipedia, so I didn't think I would have much luck. I have more information on the chemistry of nylon 11, however i am trying to decipher how to put it into my own words as it's quite technical and difficult to reword. I also have images of the structure and process for creating nylon 11, but wikipedia was giving me issues while trying to upload them. I am going to do a wikimedia commons search to see if anything has been uploaded, as those images are already approved for use.

First of all, I am impressed by the changes made thus far! This stub is feeling like a real article. I'm especially happy how the references you've found build on the library resources and publicly available information too. The comments below are just to possibly further improve things.

Introduction and table of contents:
 * Do you think it's necessary to have the reference to history in the intro section? Maybe it should just be in the history section below.
 * I also tend to avoid saying that scientists "perfected" something, unless they really did. If they instead discovered it, it's OK to say that, and realize later researchers may have improved upon their synthesis methods
 * Have you thought about the order of your sections? Is there a reason to have properties, then history, then chemistry?

Properties section:
 * When you say "It's prevalence in tubing can be seen in it's dimensional stability ...", should be its instead of it's in both instances
 * You may wish to rephrase the sentence "It's prevalence in tubing can be seen in it's dimensional stability in the presence of moisture..." to emphasize the property, rather than the application. You could in the application section emphasize why it is beneficial for tubing, while here you just focus on the properties.
 * Would it be useful to have a new first sentence to this section which gives a listing of the main properties that are different from Nylon 6? Then each following sentence would talk about those properties in order.
 * The sentence "Nylon 11 has a melting point of 180-190 °C and a glass transition temperature of about 45 °C while It's young's modulus is 335 MPa and flexural modulus is 1200 MPa at 23 °C.[3][4]" is fairly long. Maybe break it into thermal-related properties and then a separate sentence just about the mechanical properties?

History section:
 * overall I have very little change to add to this section!
 * For the sentence "Currently nylon 11 is polymerized in Birdsboro, PA, Changshu, and Serquigny.[6]", maybe an additional detail to the locations is to state which manufacturers are making it in those places.

Chemistry section:
 * Do you think the sentence "Nylon 11, or polyamide 11, is classified as a non-biodegradable polyamide bioplastic.[6]" is more of a property, or a chemistry aspect? That would determine where it would fit best. It seems a little disconnected from the rest of this section.
 * For the sentence "The chemical process of creating Nylon 11 begins with ricinoleic acid which makes up 85-90% of the supplied castor oil." What do you mean by "the supplied castor oil"?  Should you just say "castor oil"? Or is there something different about the castor oil used in this process relative to other castor oils?
 * For the sentence "This is first transesterified with methanol creating methyl ricinoleate, which is then cracked to create heptaldehyde and methyl undecylenate." It is not clear what "this" refers to in the previous sentence? Is it the ricinoleic acid? Or is it the castor oil?

Applications section:
 * For the tubing, you say "Due to it's absorption properties, ..." Do you think it'd be useful to be more specific? Perhaps you're referencing the water absorption and improved stability that was mentioned in the properties section?
 * Any idea if for any of these applications it is the primary type of polymer used in those applications? Is it dominating the market in any of these applications?

MECH 2960 Instructor Review #2
Wow! I am EXCITED about this article.

For the intro section, I think it's fine as is.

For the history section, the only change I'd recommend is that I think there's not supposed to be a space between the period and the citation? (at least, there is none when I usually see it on wikipedia). If you fix that, then I have no further edits.

For the chemistry section, I have no issues.

For the properties section, in other wikipedia articles, do they usually have the table at the front of the section, or do they normally have an introductory sentence? Right now it might be useful to have an intro sentence that says "Nylon 6 and Nylon 11 properties are compared in the table below." or something like that. Your table looks great, but I think that it is possible to find a modulus for nylon 6 somewhere to then complete the table. Instead of "glassing", you may mean "glass transition".

Applications I think works, still have the question about "due to its low absorption" whether that's water absorption?

I think after these minor tweaks you're ready to try transitioning to live wikipedia!
