Problem 4
thx so much !
Problem 1: It is desired to prepare polyester with the number average molecular weight, Mn- 5000 g/mol by reacting of 1 mol butane-1,4 diol (HO-CH2-CH2-CH2-CH2-OH) with 1 mol of adipic acid (HOOC-CH2-CH2-CH2-CH2-COOH).
(a) Write chemical equation illustrating synthesis of the polyester.
(b) Calculate the value of the monomer conversion at which the reaction should be stopped to obtain this polymer, assuming perfect stoichiometric balance. What would be polydispersity index for the polymer obtained?
(c) Assuming that 0.5 mol % of the diol is lost to polymerization by a side reaction (dehydratation to a non-reactive substance), what would be the value of Mn if the reaction was carried out to the same extent as in part (b).
(d) For the polymerization process value of polymerization rate constant is 1.5*102 L/(mol*s) at 100° C. How long would it take to prepare the polyester with the number average molecular weight, M, 5,000 g/mol at 100 ° C? There is no diol loss for this part of…
