5.2 A batch of poly(butylene terephthalate), PBT, is made by reacting butylene glycol (also known as 1,4-butane diol) with terephthalic acid, see example 2.4C. A total of 5 moles of polymer is made. The mixture contains 1.06 moles with a molecular weight of 207,900, 0.65 moles with a molecular weight of 210,100, 0.54 moles with a molecular weight of 211,420, 1.13 moles with a molecular weight of 212,080, 0.77 moles with a molecular weight of 215,160, and 0.85 moles with a molecular weight of 480,920. (Note: the above means that there are 1.06 moles of chains that have the same degree of polymerization to give the MW of 207,900, and similar for each of the other entries)
