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 ... WebAddition polymers are formed when monomer units join each other in a process that involves the rearranging of electrons in double or triple bonds in the monomer. The polymer is the ONLY product formed. EX:C=C + C=C + C=C - ·C-C-C-C-C-C· Ethene (ethylene) monomers -> part of polyethene Click the card to flip 👆 Flashcards Learn Test Match …
