The concentration of both components in water was 5 wt%. Films filled
polymers prepared according to the procedure watering.
The rheological properties of polymer solutions, organic-inorganic
compounds was studied using an Ubbelohde capillary viscometer at 20-45 °C.
The optical characteristics of the ternary organic-inorganic compounds
during polycondensation TMOS and evaporation of the solvent gave a
photometer CPK-3-01 in the wavelength region of visible light (1 = 400-700
nm).
For polymers, binary polymer-inorganic compositions using thermal
methods of analysis. DSC measurements were performed on a Netzsch DSC 204
instrument Fl Phoenix, TGA-Netzsch TG 209 Fl Ins. The heating rate was 5, 10,
15, 20 deg/min.
The study of the phase state of powders and films partially-crystalline
polymers, hybrid systems based on them was carried out by X-ray diffractometer
"DRON-3" at large angles (5 ° <20 <5O °).
IR-spectra of polymers and organo-inorganic compounds were recorded
on a Fourier spectrometer IFS-66 v/s Bruker.
The morphology of the organic-inorganic systems were determined by
transmission electron microscopy using EM - 301 Philips.
Sorption of water vapor polymers and mixtures thereof desiccator method
performed in relative humidities ranging from 20 to 98 % at 25 °C.
Deformation - research strength polymer films and composite tensile
carried out on a tensile testing machine Instron 1112.
Gelation tetramethoxysilane in aqueous solutions, hydrophilic polymers.
Reokinetika. Due to the fact that the hydrolysis and condensation reactions
begin TMOS, occur when it is mixed with water, it can be assumed that during
the process of structure formation in the reaction system contains intermediate
products of various structures, which are designated as adducts TMOS (w
TMOS).
Thus, rheokinetic studies have shown that macromolecules hydrophilic
polymers are actively involved in the formation of a network structure in
aqueous solutions of adducts TMOS. Forming dispersed particles of amorphous
silica on them followed by adsorption of macromolecular chains and,
consequently, the formation of more complex elements which are involved in the
formation of the spatial network structure. This assumption allows us to explain,
in the - first, the shift t* to lower times in solutions of poly- + measures hell
TMOS + water compared to the hell TMOS + Water. In -the second, reduced
viscosity solutions due to the high adsorption particle activity (Si02), and
depletion matrix solution (dispersion medium) polymer.
