WebPoly(ethene) is a polymer made from a very large number of ethene molecules. combined together. Forming poly(ethene) from ethene The reaction is called a polymerisation … WebPolyethylene is the most commonly and cost-effective plastic used everywhere. PE can be processed easily and can be transformed into varieties of shapes and forms. PE has the ability to alter easily during processing, thus gives relatively longer chain length, density, and crystallinity, allowing PE products to have tailored properties for a variety of applications.
