Difference Between Addition Polymerization and Condensation Polymerization

The main difference between addition and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers with no by-products whereas in condensation polymerization, the polymers are formed due to the condensation more than one different monomers resulting in the ...

What is addition polymerization give example?

Addition polymers include polystyrene, polyethylene, polyacrylates, and methacrylates. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, with the elimination of some small molecule (such as water) as a by-product. Examples include polyester, polyamide, polyurethane, and polysiloxane.

What are the two types of polymerization?

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.

What are condensation polymers give an example?

Polyamides are condensation polymers made from diamines and diacids and are named according to the number of carbon atoms in the starting materials, e.g. Nylon 6,6 is produced from hexamethylene diamine H₂N–(CH₂)₆–NH₂ and 1,6-hexanedioc acid HOOC–(CH₂)₄–COOH (commonly known as adipic acid).

Why are condensation polymers stronger than addition polymers?

Condensation polymers are therefore more rigid than addition polymers and have a higher tensile strength. The strength of the intermolecular forces between the different chains in polyamides is further enhanced by the presence of hydrogen bonding. Polyamides are therefore generally very strong.

What is the first step in addition polymerization?

This process has three stages: initiation, propagation, and termination. In the first stage, a substance is split into two identical parts, each with an unpaired electron. (Peroxides, which contain an O-O bond, are often used in this role.) A molecule with an unpaired electron is called a free radical.

Is PVC an addition polymer?

Polyvinyl choride is abbreviated to PVC. ... Polyvinyl chloride is produced in an addition polymerisation reaction using the chloroethene (vinyl chloride) monomer. This polymerisation reaction proceeds by a free-radical mechanism.

What are the polymerization techniques?

Polymerization techniques

• POLYMERIZATI ON TECHNIQUES.
• POLYMERIZATION TECHNIQUES 1. ...
• BULK POLYMERIZATION • Mass or block polymerization: Polymerization of the undiluted monomer. ...
• BULK POLYMERIZATION • The method is used for the polymerization of liquid state monomers. ...
• Advantages Disadvantages • The system is simple and requires thermal insulation.

How is polymerization being carried out?

Polymerization occurs when initiators migrate into the micelles, inducing the monomer molecules to form large molecules that make up the latex particle.

What are the 3 main types of polymers?

From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. They are commonly found in a variety of products worldwide. A wide variety of synthetic polymers are available with variations in main chain as well as side chains.

Is DNA a condensation polymer?

DNA (deoxyribonucleic acid) is an organic polymer made by the condensation polymerisation of repeating units (monomers) called nucleotides.

Which one of the following is a condensation polymer?

Dacron is a condensation polymer. The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units.

What is addition and condensation polymerization give examples?

Common examples of addition polymerization are PVC, polyethene, Teflon etc. Common examples of condensation polymerization are nylon, bakelite, silicon, etc.
