Interpretation:
Reason for configuration of a polymer of isobutylene is neither isotactic, syndiotactic, nor atactic has to be explained.
Concept Introduction:
Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as
Two types of polymers:
- Synthetic and biopolymers.
- DNA is an example for biopolymer and these type of polymers are synthesized by cells.
- Polymers synthesized by scientists are called
synthetic polymers and some examples are nylon, polyester etc.
Isotactic polymer: Substituents will be on the same side of the chain.
Syndiotactic polymer: Substituents will be on the alternate side of the chain.
Atactic polymer: Substituents will be randomly oriented.
