Polymer formed from ethene
WebTHE POLYMERISATION OF ALKENES. This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses. WebEthylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene (a hydrocarbon with carbon-carbon double bonds).. Ethylene is widely used in the chemical industry, and its worldwide production (over 150 million tonnes in 2016) …

WebIn the United Kingdom the polymer is commonly called polythene, although this is not recognised scientifically. The ethene molecule (known almost universally by its common name ethylene) C 2 H 4 is CH 2 =CH 2, Two CH 2 groups connected by a double bond, thus: Polyethylene is created through polymerization of ethene.

Condensation polymerisation involves linking lots of small monomer molecules together by eliminating a small molecule. This is often water from two different monomers, a H from one monomer, and an OH from the …
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 between the two carbon nuclei in a bond called a sigma bond.

Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following …
WebMar 8, 2024 · Addition polymers: A polymer formed by the lump sum addition of repeated monomers to end product molecules is called an addition polymer. These are formed by the repeated addition of monomer molecules possessing double or triple bonds, e.g. polythene is formed from ethene. They are again classified as: Homopolymers: These polymers are …
