Abstract—The effect exerted on the mechanical properties and thermal oxidative stability of polythiourethane
elastomers by new organomineral complexes based on 1,13-trihydroperﬂ uoro-1-propanol and montmorillonite,
introduced into the polymer in the step of its synthesis, was studied. The structural-morphological features of the
ﬂ uorinated polymer composites obtained were examined by X-ray diffraction analysis and electron microscopy.
An exfoliated composite is formed in the process.
Polyﬂ uorinated telomeric alcohols show promise as
modiﬁ ers of heterochain polymers . The properties of
these materials were improved by using organomineral
complexes of these alcohols with a clayey lamellar alu-
minosilicate, montmorillonite (MMT), as ﬁ llers for such
polymer matrices as polydiene- and polythiourethanes,
polysulﬁ des, and polycaprolactam, which can be used
for fabricating sports and waterprooﬁ ng coatings, roof-
ing materials, sealants for building, and tribotechnical
The interest in using MMT containing polyﬂ uoroalkyl
groups is due to its complex action on the supramolecular
structure of a polymer matrix ﬁ lled with it. The modiﬁ ed
MMT enhances the hydrolytic durability of composite
materials and their resistance to heat, light, and wear
owing to unique nature of polyﬂ uoroalkyl groups and to
anisotropy of the nanoﬁ ller particle shape (delamination
of organoclay in the polymer into separate nanoplates
approximately 1 nm thick and up to several hundreds of
nanometers in diameter).
This study was aimed at preparing a composite
elastomer material based on polythiourethane and
modiﬁ ed with organomineral complexes of 1,1,3-tri-
hydroperﬂ uoro-1-propanol H(CF
OH (n = 1)
Polymer composites were prepared by mixing
100 wt parts of oligobutadienediol, 5 wt parts of
glycerol, 15 wt parts of polysulﬁ de oligomer, 0.1 wt part
of urethane formation catalyst, and 3.5 wt parts of
ﬂ uorinated organoclay in a PE-8300 high-speed
mixer (shear rate 100 s
) for 6 h. Then, 24 wt parts of
polyisocyanate and 20 wt parts of manganese dioxide
(in the form of vulcanizing paste no. 9) were added, and
the components were mixed for an additional 30 min.
The resulting compound was cast into molds and kept
for 25 days at approximately 25°С.
Oligobutadienediol (Krasol LBH-3000 grade, Star-
tomer) was a polybutadiene with terminal 2-hydroxy-
propyl groups, mean molecular mass of 3000, and 1.4%
content of hydroxy groups. Polysulﬁ de oligomer (Thio-
kol, grade II, Kazan Synthetic Rubber Plant) contained
4.3% HS groups and had a number-average molecular
mass of 5500.
