2023年7月12日 · 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.

2023年10月19日 · Polymerization can be achieved through different categories such as step-growth polymerization, chain-growth polymerization, condensation polymerization and others. Polymers are long-chained compounds and their chain can even contain several thousand repeating units called monomers.

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.

Two classes of polymerization usually are distinguished. In condensation polymerization, each step of the process is accompanied by the formation of a molecule of some simple compound, often water. In addition polymerization, monomers react to …

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.

Let us do a comparative analysis of the two types of polymerization to understand them better. In addition polymerization monomers only join at the active site of the chain. But in condensation polymerization, any molecule can react with any other.

There exist several categories of polymerization reactions; the most important ones are step-growth polymerization, chain-growth polymerization (both fall under the category of addition polymerization), and condensation polymerization.

2025年1月28日 · Step-Growth Polymerization. For step-growth polymerization or simply step polymerization the key characteristics of this type of polymerization is that the monomer will typically disappear at the very early stages of the reaction.As the extent of the reaction progress, p, the molecular weight is initially very low but at the end of the reaction is increases dramatically.

There are several types of polymerizations, including: This type of polymerization involves the formation of polymers through the addition of monomers with unsaturated bonds, such as alkenes or vinyl groups. It is initiated by free radicals, which are highly reactive species that react with monomers to create a polymer chain.

Each type of polymerisation has a set of techniques using which the chemical reactions take place for the formation of polymers. Here, look at the various polymerization techniques which are used. Condensation Polymerisation . Solution polycondensation . Melt polycondensation . …
