Consider 1:1 stoichiometric polymerisation 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) Calculate the extent of reaction required to produce this polymer with a number-average molar mass of 8000.
(d) What would happen if you included 1,1,4,4-tetraaminobutane in the polymerisation so that the stoichiometric ratio was 1:2:4 tetraaminobutane:diaminobutane:sebacoyl chloride?
