WebSince ethene is a relatively stable molecule, its polymerization requires suitable catalysts. It is important to note that the conversion of ethylene into polyethylene is highly exothermic in nature. One of the most commonly used catalysts for the polymerization of ethylene is titanium(III) chloride (which is sometimes referred to as a Ziegler-Natta catalyst ). WebPoly (ethene) is a polymer made from a very large number of ethene molecules combined together. The C=C double bond in ethene is involved in the polymerisation reaction. It …
