Abstract
In one embodiment, the present invention relates to metal oxide sols comprising a liquid and a polycondensation product of about 2 to about 5,000 monomers of a partially hydrolyzed chelated metal oxide precursor. In another embodiment, the present invention relates to a process for making a metal oxide sol comprising contacting a metal oxide precursor with a multifunctional compound in a liquid to provide a chelated metal oxide precursor; contacting the chelated metal oxide precursor with a hydrolyzing agent to provide partially hydrolyzed chelated metal oxide precursor monomers; and permitting the partially hydrolyzed chelated metal oxide precursor monomers to polycondense thereby forming a metal oxide sol.
