Abstract: Microcapsules are described that include a hydrophobic core material within an acrylic polymeric shell that was polymerized from a monomeric blend that includes a mono-functional acrylic monomer as less than 25% by weight of the monomeric blend and a hyperbranched polyester acrylic oligomer as the balance of the monomeric blend, and methods of making the same. The methods include a two-stage polymerization process where the monomeric blend is polymerized with an azo-initiator in a first stage polymerization reaction and is subsequently further polymerized with a water soluble initiator in a second stage polymerization reaction.
