How To Make Polycarbonate?
« on: January 14, 2013, 11:33:59 AM »

Greet everybody,

Do anyone know how to make a polycarbonate?

What materials are needed?

Are there available any websites about how to make polycarbonate?

Thank you

Johny

That all depends on how reasonable we're all willing to be.  I just want my friends back, except for Cartman, you can keep him.

Oops, phosgène...

That you asked how to produce it let me fear you aren't qualified to use this combat gas.

-----

When producing flat plates, the most common shape, polycarbonate is cast between two glass plates, so it gets optically smooth.

No, glass plates weren't cast between two polycarbonate plates... They're cast floating on a molten metal, something like tin nowadays that mercury's hazard is recognized.

I don't understand.

Why a gas can change phase to solid?

Have a look here:
http://en.wikipedia.org/wiki/Polycarbonate
Phosgene is used as the linking agent.

It shows you the chemical reaction used to make the polycarbonate. Phosgene just reacts with the phenolic groups to produce the polymer.

Rather than talk about chemistry theory that I didn't understand, can anyone tell what materials are needed, equipments, and what process to do for easier?

Such as when we make a cake, then the materials we need are eggs, sugar, liquid milk/powder, and flour,
the equipments are a cup, stirrer, and an oven,
the process is mix them in a cup, stir them using a stirrer, and put them inside an oven.

This is not chemical theory and if you do not understand chemistry then for this particular process you will get nowhere.
Furthermore you will not be able to obtain phosgene.
I would forget it.

You need the chemical background to understand what you're doing, and how to do it sefely, so the product is under your control, and safe to handle.

So what.  You can't make a car by knowing all its pieces.  You can't make dynamite, even if you know all the components, because you have to know what you're doing thoroughly, in order to be safe.  We can't teach you years of chemistry, one posting at a time.
