Can alkenes form polymers
WebJul 23, 2024 · Alkenes can add to themselves by addition polymerisation to form 'plastic' or polymeric materials. For more details see section 7. Polymers–plastics notes; Alkenes readily burn, just like alkanes, to give carbon dioxide and water if combustion is complete e.g. complete oxidation = complete combustion WebAddition polymerisation is the reaction in which many monomers containing at least one C=C double bond form long chains of polymers as the only product. Just like in other addition reactions of alkenes, the π-bond in each C-C bond breaks and then the monomers link together to form new C-C single bonds. A polymer is a long-chain molecule that ...
