--- Quote from: Cerebus on October 06, 2018, 08:12:12 pm ---That page (about polyacrylates) says literally nothing about the matter at hand. It does not include the word isopropanol, nor any of the variations of 2-propanol's names

--- End quote ---

It says "Acrylic acid is “esterified” by reacting it with alcohols such as ethanol (ethyl alcohol) or methanol.". If they do not list all the Alcohols then it does not count?  |O


--- Quote ---or any mention of rubber swelling.

--- End quote ---

Here: "Both ethyl acrylate and methyl acrylate are flammable liquids that are prone to spontaneous polymerization, a reaction in which the acrylate molecules (at this point called monomers) link together to form long, multiple-unit molecules (polymers). "


--- Quote ---The only mention of "rubber" is in the sentence "Polyacrylates can be modified to produce a specialty rubber known as polyacrylate elastomer.".

--- End quote ---

Ignorance is bliss. You need that every question you can think of shall be answered in that one single article, otherwise whole discussion is disqualified?

--- Quote ---As it is, I've kept isopropanol in bottles with rubber seals  (in some case for so long that seals fail for mechanical reasons) and I've never had one "disintegrate".

--- End quote ---

We talk about synthetic rubbers.


--- Quote ---Have you been trying to drink it for the alcohol content? That might explain a thing or two.

--- End quote ---

You are suggesting what exactly?


--- Quote ---Like why you don't consider that the gasoline might have something to do with that seal disintegrating.

--- End quote ---

You are not only rude but ignorant or simply uneducated as well. Didn't you notice that I talk about Acrylic rubber/elastomers?

That you never make any sense, you fly off at unrelated tangents, claiming knowledge about something while at the same time demonstrating woeful ignorance of the subject in hand (like now, where you make it abundantly clear that you would not pass even a High School Chemistry exam) and then change horses in mid-stream when someone points out that you're not right, somewhat in the fashion of a person impaired by the oral consumption of gasoline.

And you are a rude nasty little man who is clearly more interested in getting a rise out of people than having a civilised discussion that might actually enlighten anyone. I and other people have tried to engage with you constructively on a number of occasions and each time you eventually just turn pointlessly rude and insulting. I could explain the litany of errors in what you've said above (e.g. further esterification as a magical expatiation of swelling in already esterified rubber, at room temperature in the absence of catalysts no less), but I know you won't listen and will just be insulting. Goodbye, don't call again.

Please do not forget that I am not only reader here. Feel free to correct litany of my errors - so other readers are not misinformed by information I provided URL's to (lol). I will not post here in this thread anymore anyway

[edit] Oh, Cerebus is  talking about that thread where he called me names as well. I will ask moderator for comment. If I am the one - so be it, in such case bye EEVBlog.

Well not wanting to or trying to piss anyone off. Just trying to convey how dangerous I think that stuff is. A relative of mine that used to sniff glue he stepped up to Toluene and walked in a moving train.
Seeing how I'm a nube, To anyone I might have offended please except my apologies, I don't have the wisdom of a Supper Contributor please forgive my naivete, I will try not to offend anyone else.

Well... if I may make an example of myself... realize that only means the user has posted a lot. ;)
