Process for preparing encapsulated phase change material particles for reusable thermal energy storage, comprising: (a) forming particles of a solid phase change material selected from the group consisting of a crystalline polymer, naphthalene, salt hydrate and a crystalline paraffin; (b) contacting said solid phase change material particles with a first reactive monomer which is terminated with reactive groups and which is in a liquid state, said first reactive monomer not being reactive with said solid phase change material particles, said first reactive monomer forming a coating thereof on the surface of said solid phase change material particles; (c) contacting said coated phase change material particles with a second reactive monomer which is terminated with reactive groups and which is in a liquid state; and (d) condensation polymerizing said first reactive monomer and said second reactive monomer to form a continuous, elastomeric, condensation polymeric shell around said particles. Encapsulated phase change material particles for reusable thermal energy storage, comprising: (a) particles of said phase change material selected from the group consisting of a crystalline polymer, naphthalene, salt hydrate and a crystalline paraffin; and (b) a continuous, elastomeric, condensation polymeric shell encapsulating said particles, said polymeric coating being formed from a first reactive monomer, and a second reactive monomer, said first reactive monomer having been coated on the surface of said particles (a) while said particles (a) were in a solid state.
