Modified poly(diorganosiloxanes), compositions, and articles comprising the same. The modified poly(diorganosiloxanes) can be soluble or dispersable in aqueous media. The articles can have modified poly(diorganosiloxanes) affixed thereto.

Compounds comprising modified diorganosiloxane polymers

Fluorinated silane compounds, compositions containing the fluorinated silane compounds, and articles prepared using the fluorinated silane compounds and compositions are described. The fluorinated silane compounds can be soluble or dispersible in aqueous media, such as water, and can be used to coat articles, such as glass articles.

Fluorinated silane compounds, compositions, and articles

Described herein is composite article comprising a substrate; and on at least one face of the substrate a multilayered coating disposed thereon. The multilayered coating comprises (i) an abrasion-resistant layer adjacent to the substrate, wherein the abrasion-resistant layer comprises inorganic oxide nanoparticles and a polymer binder; and (ii) an antireflection layer adjacent to the abrasion-resistant layer opposite the substrate, wherein the antireflection layer comprises a fluorosilane polymer, wherein the fluorosilane polymer comprises: at least one monomeric unit A represented by the formula (I) wherein Rrepresents H or methyl, Lrepresents a covalent bond or a divalent aliphatic group having from 1 to 10 carbon atoms, each Yindependently represents a hydrocarbyl group having from 1 to 6 carbon atoms, each Yindependently represents a hydrolyzable group, g is 0, 1, or 2; and at least one divalent monomeric unit B represented by the formula (I) wherein R, R, and Rrepresent H, methyl, trifluoromethyl, or F, wherein at least one of R, R, and Ris F, Rrepresents a covalent bond or a divalent group selected from the group consisting of &#x2014;(CFO)&#x2014;, &#x2014;(CFCFO)&#x2014;, &#x2014;(CFCFCFO)&#x2014;, &#x2014;(CFCFCFCFO)&#x2014;, &#x2014;(CFCF(CF)O)&#x2014;, and combinations thereof, wherein a, b, c, d, and e represent integers in the range of from 0 to 130, and wherein 1&#x2264;a+b+c+d+e&#x2264;130, and Ris a perfluoroalkyl group.
