Abstract:
1. A temperature regulating article comprising: a substrate; and a polymeric phase change material bound to the substrate, wherein the polymeric phase change material is characterized by including a precisely branched polymer with substantially equally spaced repeating sidechains each separated by carbon segments of the backbone having at least three carbon atoms, wherein the length of the carbon segments of the backbone controls a degree of crystallization of the polymeric phase change material at a given transition temperature, wherein the polymeric phase change material includes between 20 and 200 branches per 1000 carbon atoms, wherein the polymeric phase change material has a latent heat of at least 5 Joules per gram and a transition temperature between 0° C. and 40° C. dependent upon the length of the carbon segments of the backbone, and wherein the sidechains are selected from the group consisting of CH
