Why are polymers cheap?

How are they manufactured? Where do the raw materials come from?

Raw materials are coal, oil, and natural gas. These raw materials have increased in price lately, but they are far below $/lb for metals, wood, glass, which they replace. The hydrocarbon starting materials are converted to low-molecular weight compounds called monomers. The monomers are polymerized to plastic resins. The reins are fabricated into finished plastic or textile fiber goods.
Most polymers are made from the by-products of the petroleum industry- what they can't crack into gasoline, oils and gasses.
