Concept introduction: In Step-growth
(b)
Interpretation: The polymer formed from given monomer is to be predicted.
Concept introduction: In Step-growth polymerization the monomers with different functional groups combine together to form the polymer with the loss of small molecule such as water. For example polyamides, polyesters, polyurethanes, polycarbonates and epoxy resins.
