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 … WebPolymers consist of long chain molecules; natural rubber is a polymer whose molecules have no ordering. Such polymers are called amorphous. Perspex is a synthetic polymer whose structure is also amorphous. Nylon and polythene have both crystalline and amorphous regions, their structure is described as semicrystalline.The diagram below …
