Rheological investigation of sol-gel systems based on 3-methacryl-oxypropyl trimethoxysilane

Abstract

The influence of various factors (temperature, concentration of starting substances and catalyst of sol-gel process) on the rheological behavior of sol-gel systems on the basis of the organic-inorganic precursor – 3-methacryloxypropyl trimethoxysilane – was investigated by viscosimetry. The elastic and friction components of viscosity were estimated from the gradient dependence measurements using the optimization method. The integral activation energy of the gelation process in the studied sol-gel systems was calculated.
