Abstract
A stabilized phase change composition comprises a phase change material and a stabilizing agent selected from the group consisting of antioxidants and thermal stabilizers. The stabilizing agent provides oxidative or thermal stabilization to the phase change material. The stabilized phase change composition may be used or incorporated in a variety of processes (e.g., melt spinning processes, extrusion processes, injection molding processes, and so forth) to form articles having enhanced reversible thermal properties. Exemplary articles that may be formed include, by way of example and not by limitation, synthetic fibers (e.g., nylon fibers, polyester fibers, polyethylene fibers, polypropylene fibers, and multi-component fibers), fabric materials, textiles, films, foams, sheets, pellets, granules, rods, and injection molded articles.
