A silicone-polyacrylate copolymer has the formula X[ZY], 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-polyacrylate copolymer are also disclosed. Further, a sealant is disclosed, the sealant comprising the silicone-polyacrylate copolymer and a condensation-reaction catalyst.
