WebFor the homopolycondensation of N‐CBz‐Hpr with TMP initiator and SnOct 2 catalyst, the number‐average molecular weight (M n) of prepolymer increases from 530 to 3540 g mol −1 with the molar ratio of monomer to initiator (3–30), and the molecular weight distribution (M w /M n) is between 1.25 to 1.32. WebNevertheless, the data demonstrate control of molecular weights by the monomer/initiator ratio employed. 1H NMR spectra of polyglycerol (Figure 6 C) are less informative than the 13C NMR spectra but clearly confirm incorporation of the TMP initiator. The signals of the methyl and the methylene group at 0.9 and 1.4 ppm, respectively, are due to TMP.
