How are addition polymers formed
Did you know?
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 ... Web16 de abr. de 2024 · Addition polymers include polystyrene, polyethylene, polyacrylates, and methacrylates. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, with the elimination of some small molecule (such as water) as a by-product. Examples include polyester, polyamide, polyurethane, and polysiloxane.
WebYou should also be able to draw the condensation polymer formed from two given monomers, and deconstruct a polymer down into its monomers. Finally, you should have an understanding of the intermolecular forces between condensation polymer chains, and the differences between addition and condensation polymers. WebPolyethylene, polystyrene, and acrylic are examples of plastics formed by addition polymerization. These polymers are often thermoplastic in nature: they can be heated and made soft and then hardened when cooled. They are easily processed, reprocessed, or recycled. See the attached tables, Some Addition Polymers and Some Condensation …
