Condensation polymers answers
1. (a) Polyester (b) (c) n HOOC−C6H4−COOH + n HO−CH2−CH2−CH2−OH ⟶ H−(−O−(CH2)3−OCO−C6H4−CO−)n−OH + (2n−1) H2O (d) Mr (HOOC−C6H4−COOH) = (8 x 12.01) + (6 x 1.01) + (4 x 16.00) = 166.14Mr (HO−CH2−CH2−CH2−OH) = (3 x 12.01) + (8 x 1.01) + (2 x 16.00) = 76.11Total mass of 1000 mol of reactants = 166.14 + 76.11 = 242.25 kgTotal mass of water formed = 1999 x 18.02/1000 = 36.02 kgMass of polymer = 242.25 − 36.02 = 206.23...
