When lots of ethene molecules bond together, a polymer called polyethene (commonly called polyethylene) is formed. Ethene is the unsaturated monomer which, when joined to other ethene molecules through an addition reaction, forms the saturated polymer polyethene.

WebPoly (ethene) is produced in three main forms: low density (LDPE) (< 0.930 g cm -3) and linear low density ( LLDPE) ( ca 0.915-0.940 g cm -3) and high density (HDPE) ( ca 0.940-0.965 g cm -3 ). The LDPE or LLDPE form is preferred … WebThe simplest example of this is the reaction between ethene and hydrogen in the presence of a nickel catalyst. In practice, this is a pointless reaction, because you are converting the extremely useful ethene into the relatively useless ethane. However, the same reaction will happen with any compound containing a carbon-carbon double bond.
