A cross-linked composition comprises the reaction product of siloxanes having pendant anhydride groups and a reactant having hydroxyl and/or amine functional groups. The cross-linked composition can be of the following general formula (I): (I). Refer to formula ( 1 ) Each X can be of the following general formula (i): (i). Refer to formula (i) Each of W and W* is independently an oxygen atom or N—R, with R independently being a hydrogen atom or R 1 . Each of Y, R 3 , and R 13 is an independently selected divalent group. Each of R 1 , R 11 , R 4 , R 14 , R 5 , and R 15 is an independently selected substituted or unsubstituted hydrocarbyl group. Each of w and ww, and each of y and yy, is an independently selected integer from 0 to 1,000. Each of x and xx is an independently selected integer from 1 to 100. Typically, w and y are not simultaneously 0, and ww and yy are not simultaneously 0. |
