What are addition polymers and condensation polymers?
An addition polymer is made when the monomers lose an atom or group of atoms while forming the polymer. A condensation polymer is formed when monomers bond to each other without the loss of atoms. An addition polymer consists of two different kinds of monomers.
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 meant by addition polymers?
In polymer chemistry, an addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. Addition polymers are formed by the addition of some simple monomer units repeatedly. Generally polymers are unsaturated compounds like alkenes, alkalines etc.
What are addition polymers examples?
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 is the main difference between condensation polymers and addition polymers quizlet?
what is the difference between addition and condensation polymerisation? in addition polymerisation, many monomers bond together through the rearrangement of bods without the loss of an atom or a molecule, whereas in condensation polymerisation, a molecule (usually water) is lost during the formation of a polymer.
What are condensation polymers give two examples?
Examples of natural condensation polymers include cellulose, starch, and polypeptide chains of proteins. Several synthetic condensation polymers discussed include nylon, kevlar, polyester, Bakelite, Melamine, polycarbonates, polyurethanes, epoxies.
Which is condensation polymer?
In polymer chemistry, condensation polymers are any kind of polymers whose process of polymerization involves a condensation reaction (i.e. a small molecule, such as water or methanol, is produced as a byproduct). Common condensation polymers include polyamides, polyacetals, and proteins.
What is a characteristic of all condensation polymers?
Characteristics of Condensation Polymers Condensation polymers form more slowly than addition polymers, often requiring heat, and they are generally lower in molecular weight.
What is meant by a condensation polymer?
Which of the following is a condensation polymer?
Polyester is a condensation polymer; It is a synthetic fabric that’s usually derived from petroleum.
What is condensation polymer give example?
Nylon and polyesters are examples of the condensation polymers. When the monomers of hexamethylene diamine and adipic acid react with each other it gives the final product i.e., Nylon-6,6 and by-product water molecules. Polyester forms by the reaction between glycol and dibasic acid.
Which best explains the difference between a monomer and a polymer?
What is the relationship between a polymer and a monomer? Polymers are made up of monomers which are parts of a molecule while polymers are large molecules that are formed by the bonding of monomers.
What is the difference between addition and condensation?
The key difference between addition polymerization and condensation polymerization is that for addition polymerization, monomer should be an unsaturated molecule whereas for condensation polymerization, monomers are saturated molecules. Polymers are large molecules that have the same structural unit repeating over and over.
What are some examples of condensation polymers?
Examples of naturally occurring condensation polymers are cellulose, the polypeptide chains of proteins, and poly(β-hydroxybutyric acid), a polyester synthesized in large quantity by certain soil and water bacteria.
Can polymers be combined with other polymers?
It is also possible for two or more polymers to be combined with each other. When this happens, they produce an alloy or a blend. In these situations, the end product has the characteristics of each of the original components. One way to understand how polymers are created is to consider the makeup of one.
What is the relationship between a polymer and a monomer?
Monomer means “one unit,” while polymer means “many units.”. In chemistry, many compounds are polymers, large molecules that consist of repeating identical or very similar units. One way to envision the difference between a monomer and a polymer is to imagine making a chain of paperclips.
