WebTeflon is a polymer, which is made by joining together lots of smaller molecules called tetrafluoroethene (TFE). Polyethene is an addition product of ethylene. The monomer unit of PVC (Polyvinyl chloride) is vinyl chloride i.e. chloroethene. Nylon is prepared from a dibasic acid and diamine. WebStep 2: Chain Propagation. In 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 …

WebFormation of Polythene. Addition polymers are formed by the joining up of many monomers and only occurs in monomers that contain C=C bonds. One of the bonds in each C=C bond breaks and forms a bond with the adjacent monomer with the polymer being formed containing single bonds only. Many polymers can be made by the addition of alkene … WebAug 13, 2024 · 17. The scientist who coined the term polymer, Jöns Jacob Berzelius, used the word to refer to different substances which had the same empirical formula. In this sense, benzene is a polymer of ethyne (acetylene), because benzene C X 6 H X 6 and ethyne C X 2 H X 2 have the same empirical formula, namely C H. In other words, all substances … 首 吹き出物 しこり
