The polyolefin named for this compound is a linear chain of saturated sp3 carbons and is used in plastic bottles and bags.
Union Carbide's UNIPOL process polymerizes this compound, which reacts with itself over a chromium oxide catalyst in a process developed by the Phillips Company. PVC is made by reacting this compound with chlorine, then polymerizing the product. This compound is the most common product of gasoline steam cracking. Ziegler and Natta first used titanium chloride to polymerize this compound, which forms an atactic polymer classified as either (*)  "low-density" or "high-density" based on its molecular weight. Adding two equivalents of water to this compound makes the glycol in commercial antifreeze. The polyolefin named for this compound is a linear chain of saturated sp3 carbons and is used in plastic bottles and bags. For 10 points, name this two-carbon alkene.
