Polymerization: Definition, Types, and Examples - Chemistry Learner
Polymerization is a chemical reaction that involves the formation of long-chain molecules known as polymers from smaller units called monomers. Polymerization reaction occurs when multiple monomers chemically bond together, forming large, complex structures. The polymerization process can be either natural or artificial.
27.8: Polymers and Polymerization Reactions - Chemistry …
There are two general types of polymerization reactions: addition polymerization and condensation polymerization. In addition polymerization, the monomers add to one another in such a way that the polymer contains all the atoms of the starting monomers. Ethylene molecules are joined together in long chains.
Polymerization - Wikipedia
Step-growth and chain-growth are the main classes of polymerization reaction mechanisms. The former is often easier to implement but requires precise control of stoichiometry. The latter more reliably affords high molecular-weight polymers, but only applies to certain monomers.
Polymerization | Definition, Classes, & Examples | Britannica
polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
Polymerization - Definition, Types, Reactions, Polymerization …
Polymerization is a process through which a large number of monomer molecules react together to form a polymer. The macromolecules produced from a polymerization may have a linear or a branched structure. They can also assume the shape of a complex, three-dimensional network.

2023年10月19日 · Chemical reactions of organic monomers are referred to as polymerization chemical reactions. Polymers are formed by combining these monomers in infinitely long chains. This reaction includes either monomer adsorption polymerization or emulsion polymerization. Preparation of polymers is achieved through various methods.

Polymerization reactions are chemical processes in which small, reactive molecules called monomers are joined together to form larger, more complex molecules called polymers. These reactions are fundamental to the synthesis of a wide range of materials, including plastics, rubbers, and many natural and synthetic fibers.
Polymers are formed by linking monomers through chemical reaction — called polymerization. You don’t end up with a unique molecule. i monomers chain of monomers . i A → — (A-A-A )i/3— . Homopolymer:all A identical . • The most produced/used polymers are homopolymers of terminal alkenes. • Produced by radical polymerization.

In a step-reaction polymerization reaction, sometimes called condensation polymerization, the polymer chains grow by reactions that occur between two molecular species. An example is the polymerization reaction involving terephthalic acid and ethylene glycol, both of …

When the chain reaction is initiated and carried by negatively charged intermediates, the reaction is known as anionic polymerization. Like free-radical polymerizations, these chain reactions take place via chain-initiation, chain-propagation, and chain-termination steps.
