Abstract
We have synthesized the nanostructured poly(ether urethane)s of cross-linked
and branched topology by using a mixture of polyhedral oligomeric
silsesquioxanes (POSS-M) containing tertiary amine and primary and secondary
hydroxyl groups in the organic part of molecules. These compounds are
characterized by methods of IR spectroscopy, gel permeation chromatography
(GPC), atomic force microscopy (AFM), and small angle Xray scattering. The
structure of the materials is characterized by nanosized clusters enriched
with the inorganic phase forming a paracrystalline macrolattice with
hexagonal symmetry. The sizes of clusters, contents of the inorganic phase
in them, and the value of macrolattice periodicity are determined by the
topology of synthesized poly(ether urethane)s.
