The invention related to a one-pot process of making a single-phase silicone-acrylic hybrid adhesive composition comprising acrylic polymer and silicone polymer that are covalently bonded through a SiOSi linkage. The acrylic polymer contains at least one hydrolyzable silane (meth)acrylic monomer or siloxane (meth)acrylic macromer. These functional moieties provide reaction sites to form SiOSi bond by reacting hydrolyzable groups in the silicone polymer in the presence of a base or acid catalyst and water. The formed covalent bonds between the two incompatible systems of silicone polymer and acrylic polymer prevents phase separation and thereby a permanent, homogeneous single-phase system is formed.
