Concept introduction:
Polymers can be distinguished based on the functional group it has in the structure. The monomer considered for forming the polymer determines the functional group in the polymer. Few examples are,
- Acid +alcohol=polyester
- Acid+
amine =polyamide - Alcohol+phosgene=polycarbonate
- Alcohol+isocyanate=polycarbamate
(c)
Interpretation Introduction
Interpretation:
The polymer type of Quiana has to be determined.
Concept introduction:
Polymers can be classified as chain-growth and step-growth polymers. Chain-growth polymers are the one which are formed when monomer is added to the other monomer growing chain one at a time. This growing polymer chain usually has only one reactive site. This site is called growth point. Step-growth polymers are the one when the monomers react with each other to form oligomers. These oligomers are joined together to form polymers. This usually occurs when difunctional monomers are used. This has got two growth points.
