I'm the original writer of this article and just wanted to say I'm new to Wikipedia and didn't realize the copyright restrictions of the website. That said, it's nice to know there are such strict content controls for this site. Kudos. I've written a 'stub' to replace it.

As the original author of the article, I don't know what 150.202.8.1 is referring to. —Joseph/N328KF (Talk) 22:10, 16 February 2006 (UTC)

The article "Nalgene plastic may be harmful: Studies show that the popular water bottle may pose serious health risks" by Brenna Doheny, The Daily Barometer, 2004-02-17 mentions "The April 2003 volume of "Current Biology" published a study that cast suspicion on all polycarbonate plastics, including Lexan. The principle author, Dr. Patricia Hunt of Case Western Reserve University in Cleveland, Ohio" and claims that

Have there been any further studies on this? (Should this information go in the Lexan article, or one of these other articles, or perhaps the plastic article ?) --DavidCary 03:26, 27 May 2005 (UTC)

I did some reading at the time of the comment you are responding to, and it seemed clear that the concern was with PC only. The original study was motivated by fertility problems in rats living in PC cages that were subjected to specific cleaning compounds (and presumably rat body wastes and gnawing to get out); that study led to a Consumer Reports article that should not be consulted without attention to the partial retraction that CR made in response to a Nalgene demand. I'm pretty sure there were (at least then) some WP or ext lk(s) (probably the one above, but possibly in this talk-page's article or Nalgene or talk:Nalgene) that helped the start of my research.

Can someone verify that Lexan is the molecule used in Star Trek IV: The Voyage Home? DBBell 20:59, 21 December 2005 (UTC)


I lost a bet today because this article says that lexan contains chlorine! Other sources say that it doesn't. What's the deal?

The article is incorrect. While Lexan is produced from phosgene, which contains chlorine, the Lexan molecule does not contain chlorine. I corrected the article to reflect this fact. shoy 18:08, 30 June 2007 (UTC)

Of course Lexan contains chlorine, like most of the polycarbonates (only the processes which do not use Phosgene are halogen-free). Note there is no such thing as the "lexan molecule". Lexan is a brand name, while the molecule is a polycarbonate. Indeed in the polycarbonate there is no chlorine (Cl) but the plastic itselves does contain chlorine; albeit in small quantities (less than 200 ppm). —The preceding unsigned comment was added by Asterladybug (talk • contribs) 12:55, August 20, 2007 (UTC).

[edit] GE Plastics ?

GE Plastics has been bought out by SABIC. The text in the article should reflect that. --71.236.72.132 (talk) 08:17, 10 March 2008 (UTC)
