abstract = {In this work we present the synthesis of poly(1,2-butylene
oxide) (PBO) functionalized with the complementary hydrogen
bond forming groups 2,4-diaminotriazine (DAT) and thymine.
PBO is a rubbery polymer. Due to its semi-polar nature PBO
is expected to suppresses non-directed cluster formation of
the supramolecular groups but not influence their directed
interactions. For the synthesis of backbone functionalized
polymers we developed a procedure which allowed randomly
copolymerizing BO with 1,2-epoxy-7-octene using anionic ring
opening polymerization with potassium tert-butanolate as
initiator. The vinyl groups were converted to OH-groups by
oxidation. In addition, PBO with one alcoholic end group was
obtained by homopolymerization of BO. For the variant with
OH-groups at both chain ends a procedure was developed which
was based on the cleavage of the tert-butyl initiator group.
In all the polymers the alcohol groups were basically
quantitatively transformed into NH2-groups. DAT and thymine
functionalities were attached to the NH2-groups again in
almost quantitative conversion. All reaction steps were
monitored by 1H-NMR using pyridine-d5 as solvent. This
method allowed determining the conversions of the different
synthesis steps with high precision. The materials were
examined in linear rheology in order to study the effect of
the hydrogen-bonds on the dynamics of the resulting
supramolecular structures. The results corroborate the
exclusive existence of directed interactions between the
supramolecular groups.},
