Polymerization of Alkenes - Chemistry LibreTexts
WebCorrect. You want to form the more stable intermediate.You have a choice between (+)CH2-CH2Cl and CH3-C (+)HCl. In this case, the second intermediate is more stable because of resonance: a lone pair of electrons on the Cl can be delocalized into the vacant p orbital on the C. This is not ideal, because it puts a + charge on the Cl. WebHow can alkenes form polymers? By addition polymerisation. ... When making a polyester, monomers are joined together by ester linkage in a long chain to form the polymer. Polyesters can be made from a monomer containing both a carboxylic acid and an alcohol group, or from 2 monomers - one contained 2 carboxylic groups and the other containing … Web24.1: Introduction. 24.3: Anionic Polymerization of Epoxides. Polymers are long chain giant organic molecules are assembled from many smaller molecules called monomers. Polymers consist of many repeating monomer units in long chains. A polymer is analogous to a necklace made from many small beads (monomers). Many monomers are alkenes … small business halton
