The synthesis of high-molar-mass first- and second-generation, aromatic sulfonamide-based
dendronized polymers PG1(CH3) and PG1(NO2) as well as PG2(CH3) and PG2(NO2) has been
achieved. For PG3(CH3) at least oligomeric material could be obtained. The polymers exhibit
glass transition temperatures in the range of 135–
162 8C and are valuable components for a presently
ongoing in depth analysis of the persistence
length of dendronized polymers by SANS.
The corresponding monomers MG2(CH3) and
MG2(NO2) were crystallized and their structures
in the crystal determined by XRD. These single
crystals are the first ever obtained of dendritic
macromonomers. The polymerizable units were
found not to be in a proper spatial relation to
allow for a solid-state polymerization.
