Abstract

A silicone-organic copolymer has the formula Xg[ZjYo]c, where each X is an independently selected silicone moiety having a particular structure, each Y is an independently selected polyacrylate moiety, each Z is an independently selected siloxane moiety, subscript c is from 1 to 150, subscript g is >1, 0<j<2, and 0<o<2, with the proviso that j+o=2 in each moiety indicated by subscript c. Methods of preparing the silicone-organic copolymer are also disclosed. Further, a sealant is disclosed, the sealant comprising the silicone-organic copolymer and a condensation-reaction catalyst.
