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 …
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 ... Web3 de abr. de 2024 · An addition polymer is a polymer formed by simply linking the monomers with no co-generation of other products. These polymers are generally made from molecules having carbon-carbon double bonds which means addition polymers are prepared from alkenes. They are also called chain growth polymers.
WebAs well, many commercially important, addition-type permanent networks, especially those used as coatings, are synthesized via photoinitiation; − thus, it will be important for future research to focus on the photopolymerization of addition-type monomers to achieve reprocessable networks with the aid of BiTEMPS methacrylate.
