The present invention provides an alkoxy-modified silesquioxane comprising one or more compounds selected
from the group consisting of alkoxy-modified silsesquioxaues having the formula
and mixtures thereof, wherein w, x and y represent mole fractions, y does not equal zero, either w or x but not both can be zero, and w +x + y = 1.00,
wherein R 1 , R 2 and R 3 are the same or different and selected from the group consisting of (i) H or an alkyl groups having one to about 20 carbon atoms, (ii) cycloalkyl groups having 3 to about 20 carbon atoms, (iii) alkylaryl groups having 7 to about 20 carbon atoms, and (iv) R 5 X, wherein X is selected from the group consisting of Cl, Br, SH, S a R 6 , NR 6 2 , OR 6 , CO 2 H, SCOR 6 , CO 2 R 6 , OH, olefins, epoxides, amino groups, vinyl groups, acrylates and methacrylates, wherein a = 1 to about 8, R 5 is selected from the group consisting of alkylene groups having one to about 20 carbon atoms, cycloalkylene groups having 3 to about 20 carbon atoms, and R 4 and R 6 are selected from the group consisting of alkyl groups having one to about 5 carbon atoms, cycloalkyl groups having 3 to about 20 carbon atoms, and alkylaryl groups having 7 to about 20 carbon atoms. |
