ETHYL OLIGO-SILICATES WITH STRONG ACID HETEROGENOUS POLYMERIC CATALYSTS

The present invention provides a process for the synthesis of ethyl silicate with varying silica concentration, by hydrolysing ethyl silicate in varying water concentration in the presence of sulfonated catalysts having a styrene-divinyl benzene backbone. The present invention further relates to the...
