Abstract
Novel silane compositions have been prepared by reacting a 3-isocyanatopropyl trialkoxysilane with an alcohol or diol having a divalent alkylene or alkylene-ether group. The alcohol or diol has a formula weight less than about 5000. The compositions can be used to modify the surfaces of inorganic oxygen-containing materials, including but not limited to silica, silicates, borosilicates, aluminosilicates, days, and metal oxides. Surface treatment of silica nanoparticles with these compositions improves their improved dispersion in polyester nanocomposites.
