What is meant by condensation polymerization?
Condensation polymers are any kind of polymers formed through a condensation reaction—where molecules join together—losing small molecules as byproducts such as water or methanol. The main alternative forms of polymerization are chain polymerization and polyaddition, both of which give addition polymers.
What is the difference between addition and condensation polymerization Igcse?
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 are the two types of polymerization?
There are two general types of polymerization reactions: addition polymerization and condensation polymerization.
What are examples of condensation polymers?
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.
How does condensation polymerisation occur?
Condensation polymers are formed by the removal of water (or alcohols) during polymerization and the final molecular weight of the polymer is controlled by the equilibrium concentration of water or alcohols in the molten polymer at the end of the polymerization.
What do you need to know about condensation polymerisation?
Condensation polymerisation: A reaction in which two different types of monomer join together to produce a polymer and expel a small molecule such as water. Aiming for a Level 9? See if you’ve got what it takes. Test yourself with our topic questions.
How are monomers and polymers related in polymerisation?
The process of monomers (small molecules) joining up to form a polymer (long molecule) is called polymerisation. There are two types of polymerisation processes, one is addition polymerisation and the other is condensation polymerisation. The names of each polymer are linked to the names of the monomers.
