Abstract:<\/p>\n

Here we have studied an effect of a nature of adsorption-active surface of fine amorphous silica particles on cohesion-adhesion characteristics of nanostructurized blends of polyurethane elastomer (PU) with homo- or copolymers of vinyl chloride. A favorable stabilization effect on morphology of the polymer blends is provided by dense hydrogen (H-) bonding network between polymer constituents. In the silica-filled polymer blends a nano-dispersed phases of thermoplastic polymer and the filler are distributed in elastomeric matrix. Adsorption interaction of hydroxyls on the unmodified silica surface (Aerosil A-300TM) with carbonyls of polyurethane was identified by FTIR. It was found that water molecules adsorbed by a surface of hydrated silica (Lo-Vel 2003TM) or increased quantities of unmodified silica particles suppress an interaction between hydroxyls and carbonyls that was reflected in decreasing hydrogen-bonded C=O groups. Minor destabilizing impact on H-bonding network and reducing cohesion strength of the silica-filled polymer blends has hydrophobic surface of modified silica particles (Aerosil AM-300TM). Otherwise, highly hydroxylated polar surface of silicagel particles (Lo-Vel 2003TM) drastically decreases a stability of the polymer nanocomposites.<\/p>\n
