- Abstract:
- ESI-Q-TOF MS has been used for the detailed characterization of various poly(2-oxazoline)s
with different side groups (i.e. methyl, ethyl, 1-ethylpentyl, phenyl, o-difluorophenyl and
p-tert-butylphenyl) to evaluate this method as structural characterization tool for the detailed
analysis of poly(2-oxazoline)s. The results obtained
provided an understanding of the fragmentation of
poly(2-oxazoline)s, revealing the elimination of small
molecules such as ethene and hydrogen in their fragmentation
patterns, which are partially dependent on
the side groups. Also, a McLafferty rearrangement can be
a possible fragmentation route for these polymers. In
detail, side group elimination was only observed for
poly(2-alkyl-2-oxazoline)s, but not for poly(2-aryl-2-oxazoline)
s.
