WebOther condensations, such as the acyloin condensation, are triggered by radical conditions. Condensation Polymerization Reactions In one type of polymerization reaction, a series of condensation steps takes place whereby monomers or monomer chains add to each other to form longer chains. This is termed "condensation … WebMar 1, 2006 · This polymer-forming process involving the loss of a small molecule is known as condensation polymerisation. Nylon-6,6. This polymer is made by condensing two six-carbon molecules, hexanedioic acid and 1,6-diaminohexane. In industry, cyclohexane is used to make both monomers.
WebJan 23, 2024 · Condensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight. The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer … At this point, our discussion will be limited to an application of anionic polymerization. … WebCondensation polymerisation forms the polymer molecule and one water molecule per linkage. The monomers have two functional groups present, one on each end. The functional groups at the ends of one monomer react with the functional group on the end of the other monomer, in so doing creating long chains of alternating monomers, forming …
WebNylon-6,6. Nylon-6,6 is an example of a polyamide. It is made in a condensation reaction between 1,6-diaminohexane and hexane-1,6-dicarboxylic acid. This releases water. Producing nylon-6,6. Anna Brewer, StudySmarter Original. Reacting different diamines and dicarboxylic acids produces different types of nylon. WebCondensation polymerization is a step-growth polymerization where tiny molecules react with each other to make larger structural units while releasing the by-products like water …
WebMar 27, 2024 · Condensation polymerization is a form of step-growth polymerization where molecules combine, losing small molecules as by-products, such as water or methanol. It produces linear polymers from …
