FAQs on Condensation Polymerisation or Step Growth Video Lecture - Chemistry for JEE Main & Advanced

1. What is condensation polymerization?
Ans. Condensation polymerization is a process in which monomers react with each other, forming covalent bonds and releasing a small molecule such as water or alcohol as a byproduct. This process leads to the formation of a polymer chain through repeated condensation reactions.
2. How does condensation polymerization differ from step-growth polymerization?
Ans. Condensation polymerization involves the formation of a polymer chain through repeated condensation reactions, while step-growth polymerization involves the simultaneous reaction of two different monomers, resulting in the formation of a polymer chain. In condensation polymerization, small molecules are released as byproducts, whereas in step-growth polymerization, no byproducts are formed.
3. What are the advantages of condensation polymerization?
Ans. Condensation polymerization offers several advantages. Firstly, it allows for the synthesis of polymers with a wide range of properties, as different monomers can be used. It also offers control over the molecular weight of the polymer, allowing for customization of its physical and chemical properties. Additionally, condensation polymerization can be carried out under mild reaction conditions, making it a versatile and efficient polymerization method.
4. What are some common examples of condensation polymers?
Ans. Some common examples of condensation polymers include polyesters, polyamides, and polyurethanes. Polyesters, such as polyethylene terephthalate (PET), are widely used in the production of fibers, films, and bottles. Polyamides, such as nylon, find applications in textiles, engineering plastics, and automotive parts. Polyurethanes are commonly used in foams, adhesives, and coatings.
5. Can condensation polymerization be used to create biodegradable polymers?
Ans. Yes, condensation polymerization can be utilized to produce biodegradable polymers. By selecting monomers that are derived from renewable resources and incorporating functional groups that promote degradation, biodegradable polymers can be synthesized through condensation polymerization. Examples of biodegradable condensation polymers include polylactic acid (PLA) and polyhydroxyalkanoates (PHA), which find applications in packaging, biomedical devices, and agricultural films.
