    摘要： Polyester nanocomposite compositions contain silica nanoparticles that have been subjected to surface treatment with novel trialkoxysilane compositions. The novel silane compositions are prepared by reacting a 3-isocyanatopropyl trialkoxysilane with 1,3-propanediol or certain polyether diols. The silica nanoparticles exhibit improved dispersion in the polyester. This leads to haze reduction and improvements in mechanical properties.

    摘要： 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.
