ABSTRACT:
Polymeric alkoxysilanes which comprise a polymer network of the average formula ##STR1## wherein each R is an independently selected hydrocarbon or hydrocarbon ether radical, each [R']R.sup.1 is an independently selected hydrocarbon radical, all of said radicals being free of aliphatic unsaturation, a has a value from 1 to 3; and b has a value from 0.0001 to 1.0. These polymers are made by reacting an alkoxysilane of the formula ##EQU1## with water and with an organosulfonic acid of the formula R.sup.1 SO.sub.3 H. These polymers are useful in zinc-rich paints and in binders for investment castings.
