What is meant by condensation polymerisation?
Condensation polymers Some polymers are made via condensation polymerisation . In condensation polymerisation, a small molecule is formed as a by-product each time a bond is formed between two monomers . This small molecule is often water. An example of a condensation polymer is nylon.
Why is polyester a condensation polymer?
Polyester is another common type of condensation polymer. One such polyester is called polyethylene terephthalate (PET) and is formed from the reaction of ethylene glycol with terephthalic acid.
Is polyester An example of a condensation polymer?
One important class of condensation polymers are polyesters. They arise from the reaction of carboxylic acid and an alcohol.
Is polyester addition or condensation?
Polyesters occur naturally as biological polymers, but can also be made artificially. Man-made polymers are often used in clothing. Polyesters are an example of a condensation polymer.
What type of polymer is polyester?
polyethylene terephthalate
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET).
What are condensation polymers give an example?
Condensation polymers are formed by repeated condensation reaction between two bifunctional or trifunctional monomer units usually with the elimination of small molecules like water, alcohol, ammonia , carbon dioxide , hydrogen chloride , etc. For example, nylon 6,6polyester , bakelite, etc.
Which polymers are prepared by condensation polymerization?
Condensation polymerization is used to make Dacron, Nylon-6.6, and Bakelite.
What is the difference between condensation polymerization and addition 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 condensation Class 9?
Condensation. Condensation. The phenomenon of change of gas to liquid is called condensation. For instance, presence of water droplets on surface of glass containing cold water because the water vapour present in air when comes in contact with the cold glass of water it loses its energy and condenses to liquid state.
