Interpretation:
Identify whether the given polymer can be classified as chain-growth or step-growth
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.
To identify: To identify the given polymer is chain-growth or step-growth polymer.
