A series of hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane]
samples with various degrees of branching (DB) were adopted to investigate the
relationship between crystallinity and DB. The relative degree of crystallization
(DC) and DB were determined by x-ray diffraction (XRD) and 13C nuclear
magnetic resonance (13C-NMR) measurements, respectively. The corresponding
plot of DC versus DB shows quantitative dependence of the crystallinity on DB
for the polyether.
