WebDrawing Polymers. 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 … WebThis page guides you through the mechanism for the polymerisation of ethene by a free radical addition reaction. ... For simplicity we give them a general formula: Ra. 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 ...
WebJan 23, 2024 · 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. The other pair is more loosely held in an … WebMay 22, 2024 · 2.13: Polyesters. Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. The synthesis of polyesters is generally achieved by a polycondensation reaction. The general equation for the reaction of a diol with a diacid is: General synthesis of a polyester via direct esterification.
