Synthesis of COMPLETLY inorganic polymer ( No fuc**ng carbon atoms)


I want to synthesis completly inorganic polymer , I have one that i could try , it is name Polyborazylene the general formula is :




But I want to know preparation of other inorganic polymer... And the related synthesis for it.

And I want no carbon atoms in it.

thanks!

silicones contain carbons atoms in the auxillary bonds (generals formula is —[O-Si(CH3)2]n—)

Polymeric sulfur - obtained by rapidly cooling molten sulfur

polymeric sulfur nitride, an inorganic electricity-conducting polymer

And of course you probably already looked it up on Wiki so I'll save you some other wiki responses:

Inorganic Polymers

And glass, if you consider that a polymer...

To be honest I really do not like organic chemistry, but basic inorganic compound is not better because very limited, so I try to do inorganic chemistry by synthesizing complex inorganic compound.In polymer that I want to make I do not want carbon in the auxillary bonds.

Also carbon chemistry (organic) is related to explosive and illegal stuf so....

Hope to be clear, Plante1999

O yes I was forgoting , i do not consider glass like the type of polymer that i want to synthesis.

Hmmm.. the overwhelming majority of organic chemistry has neither to do with explosives, nor with polymers.

Truly inorganic polymers, free of all carbon, will be exceedingly difficult to synthesise.

It is why i want to make some , I think that to be a TRUE chemist he/she should try to make something that every other chemist thing that it is impossible and after a long time he/she could find something that have an interess , I know that I canot make some without help from Sience Madness user.
I think if I get help we can make complely inorganic polymer , but this will be realy difficult , I know that it can be absurd but I think it worth the try.

Personally I think it would be great to see a totally inorganic step-polymerization. I don't suppose anybody knows of an asymmetric inorganic coupling reaction that could be used for the purpose?

I doubt it- the bonds will never hold. I forgot the details, but a carbon-carbon bond is stronger than any other bond, so having a ring like that will probably have a tendancy to 'break apart'. If it does succeed, it would most likely be a monomer. Don't stop dreaming... start a research team!

i dont dream, an inorganic polymer is possible! check the one that is on the first post. Secondly not only carbon can form stable bond. From wath I have read inorganic polymer is more resistan to time , more tough and more durable , but at this day only a little is know about thems.

please note that the backbone chains can be made of Tin , titanium or even germanium atom from wath i read.

I am making a BIG progect of chemistry , who think is impossible , dont post.

I didn't say you were dreaming, just that it's very hard to do. Carbon is almost unique in it's ability to form saturated or unsaturated chain of unlimited length. Which is why all life (at least as we know it) is carbon based.

first I think we should find an element that could form backbone chain and could have only inorganic element atoms than we could make research for a way to polymerise inorganic compounds.

Ok it look like a crazy thing to try this , but I think it worth the cost.

That’s a subject that’s been researched to death. Higher temperature resistance of polymers is a bit of a Holy Grail of polymer research: every applied science lab of every polymers producing company in the world dreams of making such a discovery. But to date there’s almost nothing that has come to light or to fruition...

The people that would make that leap forward would be up there in the zenith of the Hall of Fame of Science…

Yes organic chemist research to the death for ORGANIC polymer , but Inorganic chemist dont. I think , with work we can make an basic inorganic polymer from organic base , ok it look like a dream, ( but it is real(inorganic polymer exist)) , but in this time where the petrol stoke goes downs the word need new type of polymer... inorganic polymers.

The inorganic polymers isn't realy know , only a little is know about them , why not explore COMPLEXE inorganic chemistry.

The polymer applied research chemists (I worked in that environment for 15 years) don't distinguish between 'organic'/'inorganic' chemistry: they'd sell their soul to find a new backbone that's unassailable by oxygen/heat/free radicals. Alas, C really is the only element amenable to forming long chains.

Units like borazylene are rare and the double bonds must cause vulnerability to chemical attack.

You shold have reason for that but why do not try to make inorganic polymer , regardless of whether it is a long molecule. I know the history that you was a rubber chemist.

Lst say that we dont have any use for it , it could still be interesting to synthesize it.

So is there anybody who wants to make an inorganic polymer?


thanks

There would be tremendous applictions for a true, non C-C polymer backbone. Except: you're trying to reinvent the wheel!

As they say: 'I'm out!'

Polysilylenes, germylenes, and stannylenes are all known, though they decrease in air stability and degree of polymerization down the group, as you might expect. Homopolymers are prepared fairly easily by Wurtz coupling of R2EX2- type monomers (E = Si, Ge, Sn). There's no reason you can't make R a borazine or borane, for example, your product is just going to be very air and water sensitive. Polyborazines themselves are fairly easy to prepare from the corresponding borazines (a quick glance at some abstracts suggests that gentle heating is sufficient), but again, organic substituents offer a lot of flexibility of stability.
