AB  - In this paper the series of poly(urethane-siloxane) copolymers and their clay
nanocomposites were synthesized based on 4,4'-diphenylmethane diisocyanate and 1,4-
butanediol as the part of the hard segments (HS) and α,ω-dihydroxy-poly(propylene
oxide)-b-poly(dimethylsiloxane)-b-poly(propylene oxide) as the part of the soft
segments (SS). Organomodified montmorillonite clay (Cloisite 30B®) was used as nanofiller
in the amount of 1 wt.% within prepared nanocomposites. Mechanical properties
and morphology of these polymers were investigated by dynamic mechanical thermal
analysis (DMTA) and wide angle X-ray diffraction (XRD) measurements.
Viscoelastic properties of the copolymers and their nanocomposites mostly depended on
the content of the HS. The storage shear (G´) and loss modulus (G") were slightly
enhanced within prepared nanocomposites, compared to the neat copolymers, due to the
addition of the clay nanoreinforcements. Moreover, prepared both series of samples had
phase separated morphology due to the existence of the multiple local segmental motions
(Tg of the HS and SS). XRD analysis revealed that clay layers were separated into an
individual layer without any regular stacking which indicates that exfoliated morphology
of the clay nano-fillers was obtained inside prepared nanocomposites [1,2].
