Abstract: Methods for producing a dimensionally stable phase change material (PCM), and dimensionally stable PCMs are disclosed. The methods include providing a porous base material, mixing a phase change material having a polar functional group with a substance that increases the polar attraction of the phase change material for the porous base material to form a mixture thereof; and, thereafter, mixing the mixture with the porous base material until a selected saturation of phase change material in the porous base material is reached. The methods may include filtering the porous base material after the selected saturation is reached to form a cake of dimensionally stable PCM and, thereafter, reducing the size of the dimensionally stable PCM to an average mean particle size of about 10 to about 50 μm, or more preferably 20 to 30 μm.

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.
