WebMacromolecules having identical constitutional repeating units can nevertheless differ as a result of isomerism. For example, linear, branched, and crosslinked polymers of the same monomer are considered as structural isomers. Another type of structural isomerism occurs in the chain polymerization of vinyl or vinylidene monomers. WebDec 11, 2015 · Monomer is a word made of two parts, mono means one, and mer means unit, so monomers are the building units of the polymers.Poly means many. …
WebApr 28, 2024 · Macromolecules are large, complex molecules. They are usually the product of smaller molecules, like proteins, lipids, and carbohydrates. Another name for a macromolecule is a polymer, which derives from the Greek prefix poly- to mean “many units.” In broken-down terms, a macromolecule is the product of many smaller molecular … WebEven if their distribution is most often low, thanks to modern polymerization, polymers’ dispersity can affect their self-assembly and reproducibility can be challenging when using different batches of the same polymers. 15 The most common polymer architecture used in forming polymersomes are di-(AB) or tri-block copolymers (ABA or rarely ABC) (where A …
WebJul 10, 2024 · Many macromolecules are polymers � large molecules made from two or more repeating units (called monomers). As an analogy, a polymer is like a freight train with many cars.
