Addition PolymersEXTENDED
Deducing the polymer from the monomer Show
Examples of addition polymerisation: polythene and PVC
Diagram showing the monomer from the repeat unit of an addition polymer (polychloroethene)
Exam TipYou should be able to draw the box diagrams representing polymers where each box represents a part of the repeating hydrocarbon chain. The functional groups on the monomers and the link formed in the polymers are the important parts and must be clearly drawn.
Condensation PolymersEXTENDED
Forming Nylon
The condensation reaction in which the polyamide, nylon is produced
Diagram showing a section of nylon Forming Polyesters
The condensation reaction in which PET is produced
Diagram showing a section of PET
Exam TipYou don't need to know the detailed chemical structure of PET, just the symbolic drawing showing the alternating blocks and the linking ester group. Be careful not to exactly repeat the linking group in nylon or PET; the link alternates by reversing the order of the atoms, rather like a mirror image. What is condensation polymer with example?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 the 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).
What is condensation polymer Example 12?Solution : 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.
Is condensation polymer a polymer?Condensation polymers are those polymers that are formed from polyfunctional monomers, which are typically prepared by the reaction between two kinds of bifunctional symmetric monomers.
What is a condensation polymer reaction?A condensation polymerization is a form of step-growth polymerization in which monomers and/or oligomers react with each other to form larger structural units while releasing smaller molecules as a byproduct such as water or methanol.
