"Cross Linker" Section

The Cross Linker section is clearly copy-pasted from a commercial website, and even advertises its products at the bottom. Candidate for deletion? 96.237.161.212 (talk) 03:20, 28 June 2010 (UTC)[reply]

Yes, removed. Materialscientist (talk) 03:27, 28 June 2010 (UTC)[reply]

Search Results

I was looking for this article, and typed in "cross linked proteins" (didn't type it in quotes). This article is nowhere near the top of the list! I don't know if there's a way to make this article come up higher ranked for that type of a search ("cross linked *"), or if the title(s) "Cross linked (or Cross-linked) protein(s)" should be made into redirects, or what.

What does anyone else think? Is there a way to rank this article higher for certain searches? Should someone go through and make a bunch of silly redirects? Is it fine the way it is (hey, I found what I was looking for, right)? — KyleP 21:28, 26 February 2007 (UTC)[reply]

Vulcanization

Is it just me, or is the vulcanization image on this page incorrect, from a chemistry standpoint? It looks like the cross-linked poly(isoprene) is missing some CH3 groups. If you look at the "vulcanization" wikipedia page, there is a very similar image, but with the CH3 groups included. I think the image on this page needs to be corrected. —Preceding unsigned comment added by 63.81.122.66 (talk) 20:17, 29 October 2007 (UTC)[reply]

The image of vulcanized isoprene is wrong. The position of the sulfur bridges is at the allylic locations in the polyisoprene chains, that is at the carbon atoms neigbouring de double bonds. The double bonds remain unchanged. — Preceding unsigned comment added by Laurens Houben (talk • contribs) 17:31, 30 June 2012 (UTC)[reply]

Reticulation

Umm, the word "reticulation" redirects here, but it's not mentioned on the page at all. Is cross-linking related to reticulation, or is this a completely bogus redirection? Thanks. 24.82.209.151 (talk) 02:33, 21 April 2008 (UTC)[reply]

the redirect should perhaps not link to this page see http://en.wiktionary.org/wiki/reticulation. Relink to network? V8rik (talk) 21:12, 21 April 2008 (UTC)[reply]

"degree of reticulation" is sometimes used interchangeably with "degree of cross-linking" (an example is its usage in this paper: Robert, C., et al. "Adhesive properties of silicone polymers on some typical opto-electronic substrates: influence of the network density." International journal of adhesion and adhesives 24.1 (2004): 55-68.)

Hyphenation

The 1986 edition of The ACS Style Guide says "cross-link" should be hyphenated.

Biological Crosslinks

Crosslinking uses

I have added a little blurb on tissue engineering, this is a major use for crosslinking. Should it be a candidate for its own subsection, or shall I just continue to beef up the generalised 'uses' section?

Alternative definition "three bonds"

Dear community, I am workng with epoxy resins, and I was very surprised to read that the IUPAC calls something a cross-link only when there are four or more chains evolving from. If you used this definition on thermosets, the entire molecular network would consist only of cross-links. We usually call it a cross-link if something (e.g., an atom) is connected to the molecular network by three bonds. For example, a primary amine that reacts twice with an epoxy group to form a tertionary amine will be a cross-link then. Wouldn't that definition be correct as well - or even more correct for that matter?--Polis Tyrol (talk) 12:36, 13 October 2015 (UTC)[reply]

Minor error in sentence of the "In Biology" section

"...play a role in atheroscelerosis trough AGEs which have..." this should be "through" :) — Preceding unsigned comment added by 145.94.7.35 (talk) 21:05, 12 October 2016 (UTC)[reply]
