Polyamides are formed by step growth reaction of aliphatic diamines with diacid. a. Suppose for a reaction, the initial concentration of aliphatic diamine and diacid were 2 moles and 6 moles, respectively. After 2 hours, the reaction has been stopped. What will be the degree of polymerization for 95% extent of reaction. b. Now suppose the initial moles of aliphatic diamines are doubled. How will it impact the degree of polymerization? c. Graphically explain the impact of initial mole ratio on the weight fraction distribution and degree of polymerization in linear step growth reaction, given that extent of polymerization is 99%.
