How is poly(ethene) formed? MyTutor

WebThe structural formula of ethene is shown in the figure below. 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. WebIn an ethene molecule, CH 2 =CH 2, the two pairs of electrons which make up the double bond aren't the same. One pair is held securely on the line between the two carbon nuclei in a bond called a sigma bond. ...
