| titleOfInvention | Method for preparing alkoxy modified silsesquioxanes |
| abstract | A method for preparing an alkoxy modified silsesquioxane comprising one or more compounds selected from the group consisting of alkoxy modified silsesquioxanes having the formula ** Formula ** and mixtures thereof, wherein w, x and y represent molar fractions, and they are not equal to zero, wox, but not both, they can be zero, yw + x + y> = 1.00, the method comprising the steps of: (a) combining in the form of a reaction mixture: (i) water , (ii) a polar protic or polar aprotic solvent for water, (iii) a solid cation exchange condensation and hydrolysis solid catalyst, and (iv) an R-trialkoxysilane, wherein R comprises a group bonded to the silicon atom and is independently selected from the group consisting of R1, R2 and R3, wherein R1, R2 and R3 are the same or different and are selected from the group consisting of (i) H or an alkyl group having one to 20 atoms of carbon, (ii) cycloalkyl groups having 3 to 20 carbon atoms, (iii) alkylaryl groups having 7 to 20 carbon atoms, and (iv) R5X, wherein X is selected from the group consisting of Cl, Br, SH, SaR6, NR6 2, OR6, CO2H, SCOR6, CO2R6, OH, olefins, amino groups and vinyl groups, where a> = 2 to 8, R5 is selected from the group consisting of alkylene groups having one to 20 carbon atoms, cycloalkylene groups having 3 to 20 carbon atoms, and R4 and R6 are selected from the group consisting of alkyl groups having one to 20 carbon atoms, cycloalkyl groups having 3 to 20 carbon atoms, and alkylaryl groups having 7 to 20 atoms carbon; (b) allow the reaction mixture to react from 0.5 hours to 200 hours to form the alkoxy modified silsesquioxanes; and (c) recovering the alkoxy modified silsesquioxanes from the reaction mixture, wherein the mixture of alkoxy modified silsesquioxanes releases from 0.05% to 10% by weight of alcohol when treated by total acid hydrolysis, and wherein the alkoxy modified silsesquioxane is free of residual acid catalyst; and wherein step (a) comprises the sub-stage of washing the strong cation exchange solid condensation and hydrolysis catalyst with water and a water solvent to remove the free acid before the addition of the solid condensation and exchange hydrolysis catalyst. strong cationic to the reaction mixture. |
