Poly(methyl methacrylate)
Hi Hamza, I've just reverted your addition to Poly(methyl methacrylate) because of a technical problem. Don't worry, it's still in the page history and it can be re-added.

The problem is that you added this to the "infobox" section of the page, the pre-formatted box at the top right of the page. These infoboxes are generated by the chembox template and they only support parameters that are already coded into the template. Glass Transition Temperature isn't one of them - it's a very general "chembox" not an infobox for polymers.

Glass transition temperature is mentioned in the article already at Poly(methyl methacrylate), but it's unsourced and I'm sure your ref could be useful there. I doubt if the parameter would ever get added to chembox as otherwise every sort of material would be shouting to have its particular characteristics added. Maybe a "polymer" infobox would be worth it though? You could try discussing this at the template's talk: page, or at the Chemistry project. Maybe there's an "other notes" option in the infobox that I'm unaware of? Andy Dingley (talk) 00:18, 26 May 2017 (UTC)

Hey Andy, As am new to Wikipedia editing so not really sure how stuff works. The point being Amorphous polymers don't have a Melting Temperature (0% crystalline) thus it's the Glass transition temperature that becomes the defining temperature for processing. That being the case here for PMMA as well. So to say they have a Melting Temperature is wrong.- Hamza


 * I'd suggest asking this at the chemistry project. I see the importance of getting the glass transition in there, but how much sense does melting point still make?  Do we have to remove that altogether?  Certainly it's not great to stick one in over the other, just because it makes it appear in the infobox.
 * It's complicated why this is a bad idea, but there's a push to support "Wikidata" and making these properties machine-readable. "Stretching" the meanings of terms in the infobox seriously degrades the value of the exported data. Andy Dingley (talk) 08:38, 26 May 2017 (UTC)


 * BTW - Prefixing your comments with an increasing number of colons shows threading on a talk page.
 * Also please sign posts on talk: or discussion pages with four tildes  as this adds a signature and timestamp. Thanks Andy Dingley (talk) 08:40, 26 May 2017 (UTC)
