WebJan 23, 2024 · Poly (chloroethene) is made by polymerising chloroethene, CH 2 =CHCl. Working out its structure is no different from working out the structure of poly (propene) (see above). As long as you draw the chloroethene molecule in the right way, the structure is pretty obvious. The equation is usually written: WebThe ethene is called the monomer and the long product molecule is called a polymer. This sort of polymer is called an addition polymer because lots of molecules have added …

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 ... WebThe polymerization of ethene or ethylene takes place by the free radical addition polymerization. Addition of polymerization involves the formation of a polymer chain by the addition of monomer units possessing double or triple bonds. Side products are not formed in addition to polymerization. It is also known as chain growth polymerization.
