The essential reaction is between phosgene and bisphenol.

∙ 15y agoPolyethylene plastic is one of the more common plastics we see every day. It is used in plastic bags, plastic sheeting (drop cloths etc.), hot melt glue and containers.
Like all plastics polyethylene is made by joining small molecules (ethylene, whiich has the formula CH2=CH2 ) together into much longer molecules. The final molecules may have many side branches (high density polyethylene) or few side branches (low density polyethylene). High density polyethylene is made in a low pressure process, low density polyethylene is made in a high pressure process. Hot melt glue is another form of the plastic known as atactic polyethylene. It's major distinction is that the molecules are not as uniform.
To make polypropylene, ethylene gas is introduced into a reactor with a small amount of oxygen in the presence of a catalyst which speeds up the reaction. Control of temperature and pressure and the choice of catalyst determines the type of polyethylene created. At the end of the reactor the polyethylene is removed from the reactants and the unreacted material is recovered for reuse.

∙ 15y agoDepends, there are various types
All are joined by Carbon and Oxygen groups in the form -O-(C=)-0-
They can also contain Allyls or Bisphenol A

Can you glue carbon fiber to polycarbonate and have a strong bond that will be resistant to weather and breaking off?
yes but no for a year long time
Is polycarbonate soluble in Tetrahydrofuran?
yes
How do you bond polycarbonate?
Depends. Are you trying to make polycarbonate from scratch, or stick two pieces of polycarbonate you already have together? If you're trying to make some polycarbonate, you do it in a factory. You start with bisphenol A. Wash the BPA with sodium hydroxide to prime it, then add phosgene. The phosgene will cause the BPA to turn into plastic resin. You do it in a factory because all three of the ingredients you use to make polycarbonate will go out of their way to kill you--in fact, phosgene was used in World War I to kill soldiers. Some things are better bought already made, and this is one of them. If you have some polycarbonate pieces already, you can glue them together or weld them. You need to heat the joint to over 600 degrees F to weld polycarbonate, but a good plastic welding machine has no problem getting that hot. Weld ON # 3 from IBS corp is and has been used for decades in the world's first Solar powered watch to bond Lexan to Lexan.The initial bond happens in 30 seconds so be ready to put clamps on.The bond is so strong after 24 hours that it frustrates people trying to pry and cut one open.To bond a Stainlees Steel plate to the lexan bottom is another story.
Is polycarbonate expensive?
I looked up the price for a 1" x 12" x 12" piece of both polycarbonate and polyacrylate, and the polyacrylate was significantly cheaper. There were several different types of polycarbonate you could buy in this size, ranging in price between $100 and $300. There was only one kind of acrylic available in the size I specified (cast acrylic) and it was about $50. If instead I chose a 1/2" x 12" x 12" the prices were closer, but the polycarbonate was still more expensive on average. There were even more types of polycarbonate in this size available, ranging from $25 to $155. There were also several types of acrylic in this size, from $15 to $40. NOTE: Prices are from the McMaster-Carr website-- see Web Links to the left of this answer. They have many many shapes and sizes for additional price comparisons if necessary!
What solvent can clean polycarbonate without damaging it?
Naphtha VM&P Grade, Kerosene and IPA can be used to clean it.
How resistant to scratches is polycarbonate sheet?
Not very. Polycarb is real strong but it will scratch.
What is the cost for polycarbonate roofing?
The cost of polycarbonate roofing depends on many things like how strong the roofing is and how much you buy. The cheapest polycarbonate roofing available costs around $10 and the most expensive ones costs around $80.
