Consider 1:1 stoichiometric polymerization of 1,4-diaminobutane with sebacoyl chloride. (a) Write down a balanced chemical equation for the polymerization. (b) Name the polymer formed by this polymerization. (c) Using the Carothers equation, calculate the extent of reaction required to produce this polymer with a number-average molar mass M – n = 25.0 kg mol−1. You should neglect the effects of end groups on molar mass. (d) Explain briefly the consequences of including 1,1,4,4-tetraminobutane in the polymerization with an exact stoichiometric ratio of 2:1:4 of 1,4-diaminobutane to 1,1,4,4-tetraminobutane to sebacoyl chloride. 3.8 A polycondensation reaction takes place between 1.
