Organic plastics are polymers, composed of monomers (repeating units). A polymer is a chain of molecules repeated again and again
these monomers will become plastic by addition polymerisation and the monomers are held by weak intramolecular forces and the forces may align themselves in a linear chain or a simple branched chain
Where do monomers come from?Most monomers come from oil.
Carbon and HydrogenDifferent kinds of monomers produce different kinds of plastics.All organic plastics include a long backbone of carbon.
Some plastics, such as polystyrene, are composed of monomers that contain only carbon and hydrogen.
Other kinds of plastics are "functionalized" with a wide variety of other kinds of atoms either present in the original monomer, or added later after polymerization.
Most amino acids can be composed entirely from carbon, hydrogen, oxygen, and nitrogen (CHON).
All the other amino acids can be composed of CHON and sulfur.
petrochemicalsToday most plastics are made from petrochemicals (crude oil and natural gas), although they can also be produced from corn and other biomasses. In manufacture from petrochemicals, refineries process crude oil to produce, first, fuels, such as gasoline, diesel, and a number of different lubricants. Then they spin off a wide variety of other petrochemicals. Some of these other petrochemicals are then used by chemical plants to make a wide variety of products such as fertilizers and plastic resins. Plastic resins are, in turn, used to produce many different types of plastic.
The majority of what we know as plastic today is made from materials that are extracted from crude oil. Often the same type of crude oil that is used to produce the fuels for cars.
- There are many other types of polymer, both natural and synthetic: cellulose, starch, silicones, Teflon, PVC, etc.
- Elementally, plastics can contain carbon (C), hydrogen (H), oxygen (O), but also nitrogen (N), chlorine (Cl), fluorine (F), silicon (Si), sulphur (S), and phosphorus (P). The term plastic merely refers to the property of being flexible but firm

How do you remove the front headlight plasctic covers on a 307 to clean inside them?
you have to take the front bumper off from underneath your car to get to the lights.
Can you spray paint a g shock?
i think you might be able to if you use spray paint that bonds to plasctic. like krylon fusion for plastic :D
What tools would you use for plastic?
Well you could use a hacksaw, a junior hacksaw, a coping saw, wet and dry paper and polish. They all work well when dealing with plasctic!!
Can examples be given to show that plastics are noncorrosive in nature?
When we go to buy any food item we generally use to carry them in plastic as plasctic do not reacts with food items as well as air and water.
Where it the fuel pump relay switch located on 1993 GMC Sierra 1500?
It is located on the firewall on the passenger side of the vehicle. It is directly below thae passengerside windshield wiper. Look for a plasctic cover with writing on the top such as "Power block" or "Fuel pump relay" or "Fuel pump Fuse"

How do you replace your rear speakers in a 1990 Lincoln Town Car?
The speakers are removed and accessed top side. There is a speaker grill extraction l made. But the grill can carefully be pried loose with one or two table type butter knives. The speakers themselves removed with the fror Phillips screws and unplugged from the speaker harness. On grill replacement it is often necessary to use a plasctic glue as age can make the grill too brittle to replace by the crimp method. The JBL speakers are 6X9's. If you're into doing a bit of soldering, you can use any high quality 3 way speaker and reduce the prices to about $35 each instead of the nearly $70 each or the originals. BTW, the door speakers are 6X6 or often referred to as 6.6" and also 3 way speakers. They are accessed by the conventional door clips. You want to be caareful here too as plastic clips get brittle.
