[edit] Vinyl chloride

Is vinyl harmful if its in dolls? —Preceding unsigned comment added by 64.148.255.56 (talk) 21:24, 31 March 2008 (UTC)

Is vinyl chloride considered "a vinyl"? The definition currently given here of a vinyl is "an organic molecule containing a vinyl group [picture of CH2=CH-R] where R is any hydrocarbon". But the next line mentions vinyl chloride (CH2=CH-Cl), and chlorine (Cl) is not a hydrocarbon. Could someone who knows clarify this? -- Jeff Q 13:37, 6 Jun 2004 (UTC)

I'm not an expert, but I believe that the "R" group can be any hydrocarbon OR a halogen (such as Cl). So vinyl chloride is probably considered to be "a vinyl." I will update the article to reflect this. -- Rockhprpenguin 03:11, Oct 16, 2004 (UTC)
The monomer behind the production of PVC is "a vinyl", but the polymer produced is not. All the double bonds are opened up in the process of addition polymerization. This is in contrast to, for instance, "acetal", which is in fact an acetal even though its monomer (formaldehyde) is not.
I just reread the question, and realized that you weren't asking about "vinyl" the polymer. Oops. I'll post this comment anyway, in case someone's curious.--Joel 01:03, 12 Jun 2005 (UTC)

[edit] vinyl in Viet Nam

Is this an urban legend? If someone can confirm it is true, please mention it in the "vinyl" article:

"Vinyl continually loses molecules from its plasticizer, ... In Viet Nam some GI’s died from blood transfusions from vinyl bottles." -- http://www.shelterpub.com/_shelter/smart_but_not_wise.html

Polyvinyl chloride - there's no vinyl in it anymore, since it's been polymerized - is virtually useless without softeners, and these may be harmful. --Vuo 21:14, 4 April 2006 (UTC)

[edit] Etymology

Could someone explain why this is related to wine? Ethanol isn't vinylic; does this come from an earlier misconception, or is it that ethenol is in wine or something? —Preceding unsigned comment added by 216.165.132.250 (talk) 20:16, August 30, 2007 (UTC)
